instance_variable_controll

Hi there
I've created some script during making on my game. This scripts controll the existence any instance in room dependence on some variable: it means, the instance can exist, only, if selected variable has current value. If not, the instance will be destroyed. Look at code and than understand.

Expand//instance_variable_controll(object,x,y,variable,value)
// Create by NicharCZ

//

var obj, variable, value, xx, yy;
obj=argument0
xx=argument1
yy=argument2
variable=argument3
value=argument4

if variable==value && !instance_exists(obj) {
    instance_create(xx,yy,obj)
    }
if variable!=value {
    if (instance_exists(obj)) { 
       with (obj) 
       instance_destroy()
       }
    }

I'm sorry for my english, that's really tragic

OK, I can see what this does, but I do not understand how it should be used. How was this used for your game?

Re: instance_variable_controll

Well, i show you some example:

I have swiching with buttons. If I click the first button, variable global.mode=1, if I click the second button, variable global.mode=2 etc.. And other object can exists only if global.mode=1.. With my script, you can select position of instance, object, variable and value itself.
