It would be nice to have a function to set what execute() should execute.
Something like this:

Code:

---

text execute_allowed_text
{
	strings = 5;
	string = "function my_function1(v_value, s_string);",	// execute my_function1 is allowed
	"function my_function2(s_string1, s_string2);",	// execute my_function2 is allowed
	"function my_function3();",				// execute my_function3 is allowed
	"skill _health;",					// execute manipulations on skill named _health
	"var variable1;",					// execute manipulations on varible named variable1
	"function wait(v_time);";				// execute wait is allowed
}

string test_string = "player._health = 100; player._mana = 50; my_function1(3, \"Hallo World\"); variable1 = 10; my_function5();";

function execute_mod()
{
	execute_allowed(execute_allowed_text, test_string);
}

---

The function execute_allowed(Text, String) should only execute...

player._health = 100;
my_function1(3, "Hallo World");
variable1 = 10;

...and ignore...

player._mana = 50;
my_function5();


This way we could make our games able for modifications without the possibility to cheat.
