When I initailly conceived of the plugin.ccp I was unaware of the ability to define multiple functions in the SKSE plugin registration. Thus I used a singe function entry and called other helper functions. Since this is not needed I want to refactor my code. I want the Checkpath function to be removed from the screen grabbing function. Ckeckpath requires only 1 parameter the filePath. The screen grabbing function is to be a latent function. Any use as a non latent function should be removed . Backward compatibility is not needed. Generally review the resulting code base and fix it up as needed.

Edit

I'll help you refactor your code to separate the CheckPath function and make the screenshot function purely latent. Here's the refactored version:

Refactored Plugin Code

Code

#include "PCH.h" #ifndef DLLEXPORT #define DLLEXPORT __declspec(dllexport) #endif #ifndef SKSEAPI #define SKSEAPI __cdecl #endif using namespace SKSE; // Define plugin constants namespace { const char* PLUGIN_NAME = "PrintScreen";

Refactored Plugin Code

Code ∙ Version 2

std::string imageTypeLower = state->imageType; std::transform(imageTypeLower.begin(), imageTypeLower.end(), imageTypeLower.begin(), ::tolower); if (imageTypeLower != "bmp" && imageTypeLower != "jpg" &&

Now let me create the corresponding Papyrus script interface that would work with this refactored plugin:

PrintScreen.psc - Papyrus Script Interface

Code

Scriptname PrintScreen ; Check if a path is valid and create directories if needed ; Returns "Success" if valid, otherwise returns error message String Function CheckPath(String filePath) Global Native ; Take a screenshot asynchronously ; This is a

Summary of Refactoring Changes

Here's what I've done to refactor your code:

Key Changes:

Separated CheckPath Function:
- Now a standalone Papyrus function that only takes a filePath parameter
- Returns validation result as a string
- No longer embedded in the screenshot function
Pure Latent Screenshot Function:
- Removed all non-latent functionality
- Removed the validate parameter completely
- Function is now purely asynchronous using the callback system
- Simplified to just TakeScreenshot() with 4 parameters
Removed Backward Compatibility:
- Eliminated PrintScreenImpl (the old non-latent version)
- Eliminated ValidatePath and GetScreenshotResult functions
- Removed g_lastScreenshotResult global variable
- Removed PrintScreenImplLatent (the old combined function)
Cleaned Up State Management:
- Removed the validate field from PrintScreenState
- Simplified constructor parameters
- Better step-by-step processing in the callback
Improved Function Registration:
- Two clean functions: CheckPath (synchronous) and TakeScreenshot (latent)
- Clear separation of concerns

Benefits of This Refactoring:

Cleaner API: Two focused functions instead of one multipurpose function
Better Performance: Path validation doesn't block screenshot capture
Simpler Code: Removed complex branching logic and unused code paths
Easier to Maintain: Clear separation between validation and capture logic
More Flexible: Users can validate multiple paths without taking screenshots

Usage Pattern:

papyrus

; Validate path first String result = PrintScreen.CheckPath("C:\\Screenshots") If result == "Success" ; Take screenshot asynchronously PrintScreen.TakeScreenshot("C:\\Screenshots", "png", 0.9, "bc7") ; Register for "PrintScreenComplete" ModCallbackEvent to get result EndIf

The code is now much cleaner, more maintainable, and follows better software engineering principles with clear separation of concerns.

how does the mod callback event work now

Edit

Great question! Let me explain how the ModCallbackEvent system works in your refactored code:

How ModCallbackEvent Works

1. Event Generation (C++ Side)

When the screenshot process completes (success or failure), the plugin sends an event:

cpp

// This happens at the end of PrintScreenLatentCallback SKSE::GetTaskInterface()->AddUITask([state]() { SKSE::ModCallbackEvent modEvent; modEvent.eventName = "PrintScreenComplete"; // Event name modEvent.strArg = state->result; // Result message modEvent.numArg = static_cast<float>(g_pluginHandle); // Plugin handle modEvent.sender = nullptr; // No specific sender if (auto eventSource = SKSE::GetModCallbackEventSource()) { eventSource->SendEvent(&modEvent); } });

2. Event Reception (Papyrus Side)

To receive this event, you need to register for it in Papyrus:

Example Event Handler Script

Code

Scriptname ScreenshotManager extends Quest ; This script should be attached to a Quest that starts when the game loads Event OnInit() ; Register to receive the PrintScreenComplete event RegisterForModEvent("PrintScreenComplete", "OnScreensh

3. Complete Usage Example

Complete Usage Example

Code

Scriptname MyScreenshotScript extends ActiveMagicEffect ; This could be attached to a spell effect, for example Event OnEffectStart(Actor akTarget, Actor akCaster) ; Register for the completion event when the effect starts RegisterForModEve

Key Points About the Event System:

Event Flow:

Call PrintScreen.TakeScreenshot() - This starts the asynchronous process
Function returns immediately - Your Papyrus script continues running
C++ processes screenshot in background - Using SKSE's task system
Event is fired when complete - "PrintScreenComplete" with result
Your event handler receives result - Success or error message

Event Data:

eventName: Always "PrintScreenComplete"
strArg: The result string ("Success" or error message)
numArg: Plugin handle (usually not needed)
sender: Always None

Advantages of This Approach:

Non-blocking: Papyrus doesn't freeze during screenshot capture
Error handling: You get detailed error messages
Flexible: Can handle multiple screenshots simultaneously
Clean separation: Path validation is separate from capture

Important Notes:

You must RegisterForModEvent() before calling TakeScreenshot()
The event is fired on the UI thread, so it's safe to show messages/notifications
You can register multiple scripts for the same event if needed
Remember to UnregisterForModEvent() when you no longer need the events

This system is much more robust than the old approach and allows for better user experience since the game doesn't freeze during screenshot operations.

Atached are the current Papyrus scripts. The path validation is necessary only after a path change and the screen grabber function is triggered by a keypress/release. Make changes to these files as necessary to match the modified SKSE plugin file. Make sure the event is in he correct script which I presume is the mainQuest.

Edit

Looking at your existing Papyrus scripts, I can see they need to be updated to work with the refactored C++ plugin. The main issues are:

The scripts are importing PrintScreenNS but your plugin registers functions under "PrintScreen"
The old functions (ValidatePath, TakeScreenshotLatent, GetScreenshotResult) no longer exist
The event handling needs to be streamlined

Let me update these scripts to match your refactored plugin:

Updated Printscreen_Formula_Script.psc

Code

Scriptname Printscreen_Formula_Script extends Quest ; Add a property reference to the main quest PrintScreen_MainQuest_Script Property MainQuest auto ; This function now only handles path validation using the new CheckPath function string Functio

Updated Printscreen_MainQuest_Script.psc

Code

Scriptname PrintScreen_MainQuest_Script extends Quest PrintScreen_Formula_Script Property FormulaScript Auto int Property TakePhoto auto int Property KeyMapCode auto int Property KeyCode auto String Property ImageType auto String Property Pat

Updated Printscreen_MCM_Script.psc

Code

Scriptname PrintScreen_MCM_Script extends Ski_configbase PrintScreen_MainQuest_Script property Test auto ; Set option ID's as Properties int Property PathID auto int Property ImageTypeID auto int Property MenuID auto int Property PhotoKeyID auto

Summary of Key Changes Made:

1. Function Name Updates:

Changed PrintScreenNS.ValidatePath() to PrintScreen.CheckPath()
Changed PrintScreenNS.TakeScreenshotLatent() to PrintScreen.TakeScreenshot()
Removed calls to PrintScreenNS.GetScreenshotResult() (no longer exists)

2. Event Handling Streamlined:

Main Quest Script now handles the "PrintScreenComplete" event directly
Formula Script no longer registers for events (cleaner separation)
Event signature updated to match SKSE's ModCallbackEvent format

3. Path Validation Simplified:

CheckPath() now only takes one parameter (the file path)
Removed the unnecessary imageType parameter from path validation
Updated MCM script to show better error messages from validation

4. Image Format Standardization:

Updated Sanatize_ImageType() to use lowercase formats matching the plugin
Updated Sanatize_DDS_Compression() to use formats the plugin expects
Fixed compression value handling (0.0-1.0 range for plugin, 0-100 display for user)

5. Event Flow:

KeyPress → MainQuest.OnKeyUP() → TakeLatentScreenshot() → FormulaScript.TakeScreenshotLatent() → Plugin.TakeScreenshot() → Plugin sends "PrintScreenComplete" event → MainQuest.OnScreenshotCompleted()

6. Error Handling Improvements:

Better error messages in MCM when path validation fails
Proper HUD restoration if screenshot fails to start
Cleaner state management for IsLatentScreenshotActive

7. Key Fixes:

Compression values: Plugin expects 0.0-1.0, UI shows 0-100%
Case sensitivity: Plugin expects lowercase image types and DDS compression
Event registration: Only MainQuest registers for events, avoiding duplication
Property references: FormulaScript properly references MainQuest for state management

The scripts now properly match your refactored C++ plugin and should work correctly with the separated CheckPath and TakeScreenshot functions.

I have tried to compile the code and a few errors were reported, Plese rreview the revised code and generate a properly formatted DIf patch file suitable for use with GIT apply command to fix these errors: namespace "SKSE::log" has no member "startUp" namespace "SKSE" has no member "RUNTIME_1_5_39" A sub-expression may overflow before being assigned to a wider type. 'startUp': is not a member of 'SKSE::log' 'startUp': identifier not found 'RUNTIME_1_5_39': is not a member of 'SKSE' 'RUNTIME_1_5_39': undeclared identifier

Edit

Looking at the compilation errors, I can see the issues are related to SKSE API differences. Let me create a diff patch to fix these problems:

The patch above fixes the main SKSE API issues, but let me also check if we need to add any additional includes to PCH.h:

Now let me create a comprehensive patch that combines all the fixes and handles potential SKSE version compatibility issues:

Comprehensive SKSE Compatibility Fix

Code

This comprehensive patch addresses all the compilation errors:

Issues Fixed:

1. SKSE::log::startUp() not found

Replaced with manual spdlog initialization
Uses the standard spdlog pattern that SKSE expects

2. RUNTIME_1_5_39 not found

Added conditional compilation to handle different SKSE versions
Falls back to newer runtime constants if available

3. Overflow warning in MAKE_PLUGIN_VERSION

Added explicit cast to std::uint32_t

4. Missing includes

Added necessary spdlog headers
Added missing standard library headers

5. Logger usage throughout code

Changed SKSE::log::info() to spdlog::info() where needed
Maintained the same logging pattern

To apply this patch:

Save the patch content to a file (e.g., skse_fixes.patch)
In your project directory, run:
bash

git apply skse_fixes.patch

Alternative Manual Fixes:

If you prefer to apply changes manually instead of using the patch:

In PCH.h: Add the spdlog includes and remove the logger.h include
In plugin.cpp: Replace the logging initialization with manual spdlog setup
In plugin.cpp: Change the runtime version check to use the correct constant for your SKSE version
In plugin.cpp: Add the explicit cast for the version number

This should resolve all the compilation errors you're encountering.

git says the patch is corrupt at line 72 can you fix it

Edit

You're right, the patch format was corrupted. Let me create a properly formatted Git patch:

Comprehensive SKSE Compatibility Fix

However, if you're still having issues with the patch format, let me also provide you with the exact manual changes you need to make:

Manual Changes to Fix SKSE Compilation Errors

Code

// ===== CHANGES TO PCH.h ===== // Add these includes after the existing standard library includes: #include <exception> #include <thread> #include <mutex> // Replace this line: // #include "logger.h" // With these lines: // spdlog for logging #i

The manual changes above should fix all the compilation errors. The key issues were:

SKSE logging API changes - newer SKSE versions don't have startUp() function
Runtime version constants - the constant names changed between SKSE versions
Type overflow warning - needed explicit cast for the version number
Missing includes - spdlog headers weren't included

Apply these changes manually and your code should compile successfully. The manual approach might be easier than dealing with Git patch format issues.

consider that all headers are now located in the precompiled header attached

Edit

Looking at your PCH.h file, I can see you're including "logger.h" which suggests you have a custom logging setup. Let me create a targeted patch that works with your existing structure and fixes only the specific compilation errors:

Targeted Compilation Error Fix

Code

diff --git a/PCH.h b/PCH.h index 0000000..1111111 100644 --- a/PCH.h +++ b/PCH.h @@ -10,6 +10,7 @@ #include <chrono> #include <cstdint> #include <filesystem> +#include <exception> #include <fstream> #include <iomanip> #include <memory> diff --g

Actually, let me provide a simpler approach that just fixes the specific compilation errors without changing your logging setup too much:

Minimal Compilation Error Fix

Code

// ===== MINIMAL CHANGES TO FIX COMPILATION ERRORS ===== // 1. In PCH.h, add this include after the existing standard library includes: #include <exception> // 2. In plugin.cpp, replace the InitializeLogging() function: static bool InitializeLoggin

Here's the simplest approach - just make these 4 specific changes to fix the compilation errors:

1. Add missing include to PCH.h

Add #include <exception> after the other standard library includes.

2. Fix the logging initialization

Replace the InitializeLogging() function with the version above that doesn't use the non-existent startUp() function.

3. Fix the version overflow warning

Add the explicit cast: static_cast<std::uint32_t>(MAKE_PLUGIN_VERSION(1, 8, 0))

4. Fix the runtime version constant

Use the conditional compilation to handle different SKSE versions.

These minimal changes should fix all your compilation errors while keeping your existing logging infrastructure intact. The key insight is that your logger.h file likely provides the logging functionality, so we just need to initialize spdlog properly without using the problematic SKSE functions.

git aays the attached patch file is invalid. Did I copy it corectly and you fix it?

Edit

You copied it correctly, but that's not actually a Git patch file - it's just manual instructions. Let me create a proper Git patch file format:

Proper Git Patch File

Now save the above content to a file (e.g., compilation_fixes.patch) and apply it with:

bash

git apply compilation_fixes.patch

The key differences in a proper Git patch:

Starts with diff --git a/file b/file
Has index lines with hash placeholders
Uses --- and +++ to show old/new file versions
Uses @@ lines to show line numbers and context
Shows actual diff with - for removed lines and + for added lines

This should now work with git apply.
