[ZScript] Ported Action functions

[Kizoky]

What's the purpose of this?
Maybe you want to study how A_Chase works in GZDoom, or maybe A_LookEx but without having to look up the original source code?

Or maybe you want to create your own A_Chase on top of the original one?

Here is a collection of action functions that aren't exposed to ZScript, but can be ported.
Note: I'm trying my best to retain the way the original code is written along with comments, so it shouldn't be confusing when compared to C++ implementation

A_Chase: https://github.com/Kizoky/CPPtoZScript/ ... _Chase.txt
A_LookEx: https://github.com/Kizoky/CPPtoZScript/ ... LookEx.txt
A_Wander: https://github.com/Kizoky/CPPtoZScript/ ... Wander.txt

Alternatively you can look below for downloading them

Thank you, very useful for me.

I am developing a new behavior and I need information about "Chase" and about "SetGoal".

Ohhh man this is unbelievably useful! How hard would it be to do a port of A_LookEx?

Depends on if every function in A_LookEx is available (exposed to) in ZScript
From the looks of it it's possible to port it, it's in p_enemy.cpp (at line 1874)

Edit:
I ported A_LookEx, here's a link for it here: https://github.com/Kizoky/CPPtoZScript/ ... LookEx.txt
Hopefully I didn't mess up anything with it

Wow, using redefined functions vs the hacky and probably unsupported method I was using before is so much easier. Thank you for this.

I finally got a chance to try these out and without making my own modifications, they don't work as-is. When adding them to an actor, they don't seem to work without any arguments set like the regular functions do. For example, when I do set arguments for A_PortedLookEx, it errors out when using "See" for the seestate variable. If I use seestate instead it does work but monsters wont react to seeing me, only hearing me. A_PortedChase does work without arguments but monsters wont attack me.

Ouch. There must be something that I screwed up accidentally, I'll look into it asap
