Hello. I am rather amateurish with sourcemod. However, I am able to change an antlions health using:
Code:
SetEntProp(ent, Prop_Data, "m_iHealth", 500);
But, I cannot do this with a certain bool value named "IsAllied". (Check link below)

https://github.com/ValveSoftware/sou...lion.cpp#L3814

Is there a way to force the value to be 1 despite it checking for globals?

I find it hard to believe both m_iHealth and "IsAllied" are meant to be Prop_Data. Can you try Prop_Send?

That doesn't work. Also, m_iHealth works.

Alright:

sm_dump_datamaps datamaps.txt
sm_dump_netprops netprops.txt

Then send me both files.

...is this HL2 single player game ?

And IsAllied() is function. You Maybe need look signature of it and use DHooks or else.

It's for hl2dm, but I'll look into DHooks.

This is what I have found (hl2mp). I'm not 100% sure do these work.
I guess Linux have this one signature ?
But on windows, it get complex some reason :/
Code:
Linux
_ZN12CNPC_Antlion8IsAlliedEv

windows
56 8B F1 83 BE 24 09 00 00 04
55 8B EC 53 57 68 ? ? ? ? 
55 8B EC 53 8B D9 56 8B 75 08 57 8B BB A4 0F 00 00 
...on windows, I can't get signatures of these.
Code:

*edit
I added Netprops and Datamaps dumps into this post as well. If you like look those.
These are again offsets things. I did not find "IsAllied" from there.
