Yeah will do. You'll have to give me some time.. I was adding some new natives but they're not working 100% yet. When that's done I'll release with the new forward.

Edit: Completed.

You can improve the signatures with these:
L4D1:

PHP Code:

/* From "server.dll" */
Signature for detouring sub_1029F820 (CTerrorPlayer::MaterializeFromGhost):
"\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\xFF\x2A\x50\xE8\x2A\x2A\x2A\x2A\x50\x8D\x86"
/* ? ? ? ? ? ? ? ? ? ? ? FF ? 50 E8 ? ? ? ? 50 8D 86 */ 


L4D2:

PHP Code:

/* From "server.dll" */
Signature for detouring sub_1031D120 (CTerrorPlayer::MaterializeFromGhost):
"\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x2A\xFF\x2A\x50\xE8\x2A\x2A\x2A\x2A\x83\x2A\x2A\x50\x8B\x2A\x8B\x90\x2A\x2A\x2A\x2A\x8B\x2A\xFF\x2A\x50\x68\x2A\x2A\x2A\x2A\xE8"
/* ? ? ? ? ? ? ? ? ? ? ? FF ? 50 E8 ? ? ? ? 83 ? ? 50 8B ? 8B 90 ? ? ? ? 8B ? FF ? 50 68 ? ? ? ? E8 */ 


You could also probably wildcard some more bytes to make them more durable.

Done.

This don't seem right. Maybe you copy pasted the wrong description?

[Silvers]

Thanks, fixed.

1.44 (01-Jul-2021)
    - Fixed forward "L4D_OnMaterializeFromGhost" not firing. Thanks to "ProjectSky" for reporting.
    - Fixed changelog description. Thanks to "Spirit_12" for reporting.

This is a bit confusing:

Then call "L4D_TakeOverBot" then call "L4D_SetHumanSpec

It should be like this?

First "L4D_SetHumanSpec", then "L4D_TakeOverBot"

[Silvers]

You're right, thanks for reporting the mistake. Test plugin shows correct usage.
