Code:

......

{$c}

void demo(int a){
int temp = a;
{$lua}

print(temp)

{$asm}

}

{$asm}

......

The above writing is wrong, how can I call lua's print or call in c :?

do you want to call the game's lua or ce's lua?

if ce's lua and assuming a 64 bit target:

Code:

alloc(callprint,16)
callprint:
{$luacode param1=rcx retvalue=rax}
print(param1)
{$asm}
ret

{$c}

void demo(int a){
int temp = a;
callprint(a);

}

{$asm}
