Ok, so the manual states that execute() is for "executing an engine function or variable assignment from a character sequence." - I take it that this means i can only use execute() to change engine variables (like camera.clip) and not other variables (like var my_var;). Is this a correct assumption? Also is there some way to change the value of my_var with an execute() type function during runtime?

Your assumption is right. You can change self-defined variables with var_for_name. See http://www.conitec.net/beta/var_for_name.htm.

EDIT@widi: Haha!

This is correct. Also in the manual:

For altering script variables, use var_for_name.

inkey(TEST_STR);
if (13 == result) var_for_name(TEST_STR);


EDIT: with my tests if var_vor_name works, Uhrwerk was faster...

Ok, so i tried:

function* function_ptr(var my_var);

function my_func(var my_var)
{ <code>
}

function main()
{ STRING* exec_str = " ";
str_cpy(exec_str,"function_ptr = ");
str_cat(exec_str,"my_func");
var_for_name(exec_str);
if(function_ptr)
{ function_ptr(1);
}
}

This does not work. function_ptr gets set to NULL instead of the function. Can you not use var_for_name to reassign function pointers? You can only use it to change var type variables, i guess?

Yes, your are right. You can changed fixed, i.e. var variables and Strings. I have never tested it with int or double variables. Just try it. For calling functions you can use http://www.conitec.net/beta/engine_getscript.htm.

Alright! engine_getscript() did the trick....almost. heh

I tried:

STRING* my_str = "my_func";
void* myfuncptr(var my_var);

function my_func(var my_var)
{ <code>
}

function main()
{ myfuncptr = engine_getscript(_chr(my_str));
if(myfuncptr)
{ myfuncptr(1);
}
}

It turns out that engine_getscript specifically requires a char* array, a STRING* doesnt work (engine_getscript returns NULL if you use a STRING*) so I had to use _chr() to convert the STRING* to char*

You can just use "engine_getscript(my_str->chars);" for this purpose.
