OpenRCT2 Crash: InputStateWidgetPressed Error Analysis

Experiencing crashes while playing OpenRCT2 can be frustrating. This article delves into a specific crash report related to the OpenRCT2::InputStateWidgetPressed function, providing a comprehensive analysis to help understand the issue and potentially find solutions. We'll break down the error details, examine the callstack, and discuss potential causes and troubleshooting steps.

Understanding the Error: OpenRCT2::InputStateWidgetPressed

This error, identified by the fingerprint 6126c6212a700b70f0e561b2e300f7b89a1482941ae125f86f35e644411ac05b, points to a problem within the OpenRCT2::InputStateWidgetPressed function. This function is crucial for handling user input, specifically when a widget (a user interface element like a button or a slider) is pressed. When this function encounters an issue, it can lead to a crash, disrupting your gameplay.

The error report indicates that this is a new error, with only one occurrence reported since December 3rd, 2025. This suggests that the issue might be relatively recent or triggered by specific circumstances. The application affected is openrct2.exe, which confirms the crash occurs within the OpenRCT2 game itself.

Key Attributes of the Crash

Several attributes provide valuable clues about the nature of the crash:

• Application: openrct2.exe
• Error Message: EXCEPTION_ACCESS_VIOLATION_READ - This is a crucial piece of information. An access violation error, particularly a read violation, means the game tried to read memory it didn't have permission to access. This often points to a bug in the code where the game is trying to access an invalid memory address.
• Version: OpenRCT2, v0.4.29 (ebe87be3da) provided by GitHub - Knowing the game version is essential for developers to track down the bug and for users to determine if they are running a version with known issues. The commit hash ebe87be3da provides even more specific information about the exact build.
• Callstack: The callstack is a list of functions that were called in sequence leading up to the crash. It's like a trail of breadcrumbs that helps developers pinpoint the exact location of the error.

Analyzing the Callstack: Tracing the Error

The callstack provided in the report is instrumental in understanding the sequence of events that led to the crash. Here's a breakdown of the callstack:

1. OpenRCT2::InputStateWidgetPressed - This is where the crash occurred, as we already know.
2. OpenRCT2::GameHandleInputMouse - This suggests the issue is related to mouse input handling within the game.
3. OpenRCT2::GameHandleInput - This is a more general input handling function, indicating the problem stems from processing input events.
4. ContextHandleInput - This function likely manages the context in which input is handled.
5. OpenRCT2::Context::RunFixedFrame - This function is part of the game's fixed-time step update loop, which handles game logic and physics.
6. OpenRCT2::Context::RunFrame - This is the main game frame update function.
7. OpenRCT2::Context::RunGameLoop - This function contains the primary game loop, continuously updating and rendering the game.
8. OpenRCT2::Context::RunOpenRCT2 - This is the entry point for running the OpenRCT2 game.
9. NormalisedMain - This is a platform-agnostic main function.
10. wmain - This is the standard Windows main function.
11. invoke_main - This function invokes the main function.

By tracing the callstack, we can see that the crash originated from the OpenRCT2::InputStateWidgetPressed function, which was called as part of handling mouse input during the game's main loop. This strongly suggests that the issue is triggered when the game processes a mouse click or interaction with a widget.

Potential Causes and Scenarios

Based on the error message and callstack, several potential causes could be behind this crash:

• Invalid Memory Access: The EXCEPTION_ACCESS_VIOLATION_READ error strongly suggests the game attempted to read from a memory location it wasn't authorized to access. This could be due to a pointer error, accessing a deallocated object, or a buffer overflow.
• Null Pointer Dereference: The game might be trying to access a member of an object through a null pointer. This happens when a pointer variable doesn't point to a valid memory location.
• Race Condition: If multiple threads are accessing and modifying the same data related to input handling, a race condition could occur, leading to memory corruption or unexpected behavior.
• Corrupted Game Data: It's possible that game files or saved data are corrupted, causing the input handling to malfunction.
• Mod Conflict: If you're using mods, a conflict between them could lead to unexpected behavior and crashes.
• Bug in OpenRCT2 Code: It's also possible that there's a bug in the OpenRCT2 code itself, specifically within the input handling logic.

Troubleshooting Steps: Resolving the Crash

If you're experiencing this crash, here are some troubleshooting steps you can try:

1. Update OpenRCT2: Ensure you're running the latest version of OpenRCT2. Developers often release updates to fix bugs and improve stability.
2. Disable Mods: If you're using mods, try disabling them one by one or in groups to see if any particular mod is causing the crash. Start by disabling recently installed or updated mods.
3. Verify Game Files: Some game launchers have an option to verify the integrity of game files. This can help identify and replace corrupted files.
4. Check Graphics Drivers: Outdated or corrupted graphics drivers can cause various issues. Update your graphics drivers to the latest version or try rolling back to a previous version if you suspect a recent driver update is the culprit.
5. Run OpenRCT2 as Administrator: Running the game with administrator privileges can sometimes resolve permission-related issues.
6. Check for Conflicting Applications: Some applications might interfere with OpenRCT2. Try closing unnecessary applications running in the background.
7. Reinstall OpenRCT2: If none of the above steps work, try reinstalling OpenRCT2. This can ensure a clean installation and eliminate any corrupted files.
8. Examine Crash Dumps: OpenRCT2 generates crash dump files when it crashes. These files contain detailed information about the crash and can be helpful for developers to diagnose the issue. If you're comfortable sharing these files, you can post them on the OpenRCT2 forums or issue tracker.
9. Check OpenRCT2 Forums and Issue Tracker: Search the OpenRCT2 forums and issue tracker for similar reports. Other users may have encountered the same issue and found a solution, or developers may be aware of the bug and working on a fix.

Further Investigation: Digging Deeper

For developers or experienced users who want to delve deeper into the issue, here are some additional steps:

• Analyze the Crash Dump: Crash dump files can be opened with debugging tools like WinDbg or GDB. Analyzing the crash dump can provide more specific information about the state of the game at the time of the crash, including the values of variables and the contents of memory.
• Reproduce the Crash: Trying to reproduce the crash in a controlled environment can help narrow down the cause. Try to remember what actions you were taking in the game when the crash occurred and attempt to replicate them.
• Use a Debugger: Attach a debugger to the OpenRCT2 process and step through the code in the OpenRCT2::InputStateWidgetPressed function and surrounding code. This can help identify the exact line of code where the crash occurs and the values of relevant variables.

Conclusion: Addressing OpenRCT2 Crashes

The OpenRCT2::InputStateWidgetPressed error, as indicated by the EXCEPTION_ACCESS_VIOLATION_READ message, points to a memory access issue within the game's input handling logic. By analyzing the callstack and considering potential causes like invalid memory access, null pointer dereferences, or race conditions, we can start to narrow down the source of the problem.

By following the troubleshooting steps outlined in this article, users can attempt to resolve the crash and get back to enjoying OpenRCT2. If the issue persists, further investigation using debugging tools and analysis of crash dumps may be necessary to identify the root cause.

Remember to keep your game updated, manage your mods carefully, and utilize the OpenRCT2 community resources for assistance. Reporting the issue with detailed information, including the crash dump, can significantly aid the developers in fixing the bug.
