Hi everyone, i trying to register own lua function to the game by:

int luafunction() {
	return 2+2;
}
FramescriptRegister("mynewluafunction", (int)luafunction);

After calling /dump mynewluafunction() in game i have

Dump: value=mynewluafunction() 
[1]=<function [DevTools_Dump]>, 
[2]=value, 
[3]=<function>, 
[4]=<function [DevTools_Dump]>  

instead of returning 4
Also tryed

char* luafunction() {
	return "test";
}

it returns

Dump: value=mynewluafunction()
empty result

I feels that question is very stupid but i'm missing something...

Thats not how lua works.
You need to push return values onto the lua stack. The return value of your function is the amount of return values pushed onto the stack.

Finally someone added all the proper information to figure out a lua problem. Far too many miss the php and html code

Thanks! It works by

int luafunction(int state) {
	FrameScriptPushNumber(state, 7);       // we want to get 7 as result
	return 1;                                                      // number of result to be returned
}

Dump: value=mynewluafunction()
[1]=7

I have one missunderstading.
I trying to get arg value by

inline auto FrameScript_ToNumber(int Lstate, int arg)
{
	return ((double(__cdecl*)(int, int))0x0084E030)(Lstate, arg);
}

always return 0, if i checks the arg by FrameScript_IsNumber, it can read and return 1 if it is a number, athoerwise 0

inline auto testint(int Lstate, int arg)
{
	double arg = FrameScript_ToNumber(Lstate, 1); //always 0
	return 1; 	//return arg as argument from call
}

on return 1, i see my arg, but how can i extract it from argument from call, i cant understand

-------------------------------------------
Nvm, its worked, don't know why it didn't work before
