Making an object show only once?

[BoshyMan741]

Does anyone here know how to make objects only appear once. (In Gamemaker 8.1) Kinda like the warnings in Happil 2 how they only appear once until you reset/press esc. No one on skype knew how.

Make it a persistent object. Have it become invisible instead of destroying itself, and it destroys itself on the room end event

Global variables would do the trick. Simply do something similar to this.

Code: [Select]

If global.warning[1] = 0 {
      // put your warning script here
      global.warning[1] = 1;
}
Global variables are persistant until you close or reset the game (or until you reset them to 0 manually). The number 1 within the square brackets can be changed so you can have many different warnings in your game.

Thank you!

Oops... By reset I meant as in pressing F2 not R. Is there a way to change it?

If it shows every time you press R it's because you manually set it to 0 in that room or it's not global.

If your global variables are reseting to 0 when you press "R" you might be having a problem with the engine.

Check the load scripts and make sure the game doesn't have a restart_game in there. If you do that however, you might have other problems with global trigger variables wich you will need to set to 0 when pressing "R". (before the loadGame script is executed)

Yep that was the problem too.  I fixed the other global variables too. Thanks.
