I know this has nothing to do with Mario at all. But I need help on how to deal with the checkpoint. EXAMPLE: If I get destroyed before the checkpoint reach, then it reaches be back at the stage. Then, at the certain point, I teleport towards that checkpoint and continue on. It seemingly seems difficult for me to figure out. [img]http://i.imgur.com/CU8pDiF.gif[/img] 1st part: When destroyed at the beginning, I reset back towards my origin (sorry I didn't show you that) 2nd part: When destroyed after the point, my position will be on the checkpoint. *BTW, I'm using Game Maker Studio for this.

Create an object called obj_checkpoint. Don't give it any sprites. Step event: [code]if (obj_player.x > x) { global.checkpointx = x instance_destroy() }[/code] Now add this to the create event of the player [code]x = global.checkpointx[/code] Be sure you reset the checkpoint variable after finishing the level.

I did what you want me to do, but it gave me this: [img]http://i.imgur.com/mrk9ifs.png[/img]

If you aren't aware why you get that error you should probably watch some coding tutorials starting from zero. No offense but you won't be able to put together a game (if the coding depends on you) if you don't know how to initialize a variable.

[quote="SonicZetrex"]I did what you want me to do, but it gave me this: [img]http://i.imgur.com/mrk9ifs.png[/img][/quote] You forgot to set global.checkpointx=0 at the beginning of the game. At game start. Or preferably, I suggest you make the first room one filled with global variables in the creation code tab, followed by good old room_goto_next(). It will also aid in learning Save/Load functions in GMS. Also, another tip: set global.checkpointx to 0 at the end of a level as well, but not in room end. Make an object to collide with that will end the level.

Yeah I thought you would know how to initialize a variable, that's like one of the most basic things in coding.

(Mors) I will never forgive myself...I didn't even know that your method can actually work. (DJ Coco) Yes, I know how to initialize the variable. It's just that I didn't know that I supposed to do it in a room, not in an object. (Mocgames998) Thank you for giving me a hint for putting it in a room instead of an object. I'm an insolence sometimes, but mostly I know what I'm doing.

You can initialize the variable any way you want, it just has to be before you use it.
