Mouse Wheel Scroll
Authors: KK20
Version: 1.0
Type: Input Add-on
Key Term: Misc System



Introduction

This script allows the use of scrolling the mouse wheel. It was written as an extension to Blizzard's Mouse Controller:
http://forum.chaos-project.com/index.php/topic,4710.0.html

Note that this script is not necessarily complete. It is up to you, the developer, to make use of this script's features. I only added the ability to scroll through Window_Selectable contents.


Features


  • Players can scroll the mouse wheel

  • Additional configuration option to allow the cursor to be visible at all times

  • Windows_Selectable#update allows the ability to scroll through the windows via mouse wheel




Screenshots

None.


Demo

None.

Author's Notes

Performance might be slow on terrible computers. I would appreciate it if people can test this for me.
If you wish to adapt this script to other existing mouse controller scripts, you are free to do so.

it seems... not compatible with my Windows 7 Ultimate (Service Pack 1)

KK20, you should probably check my linker settings in XPA_Window. Mine works on XP SP3 and higher.

But does this only apply to this script or all my DLLs? I wonder if it has anything to do with the window events or creating a thread.

Likely all DLLs if you are using the same compilation settings. I set up mine to use the minimum of dependencies and to link to static libs so no extra stuff is needed. Handling window events and creating a thread shouldn't be a problem. Though, it might not be a bad idea to run Game.exe as admin to see if that is the problem.

I just installed a Win7Ultimatex64 VM to test it out. I think I uploaded the wrong version of the DLL, one that was using some optimization [-O2] (this is set by default :\ ). On my Windows10, it just gave me a critical error.

Anyways, the version I've been using for my tests is here: -removed-

Worked on my end.
I'll update the dropbox link when I get back home.
Edit: Done.
