How do you make a parallax game?

[Depraved Spirit 💀]

I am trying to make a side scrolling game with a 3D illusion using layers, I am using a code like this:

if (self.y < PlayerObj.y) {
depth = 1
}
if (self.y > PlayerObj.y) {
depth = -1
}

But the problem is, that I have a lot of enemies plus the playable character and I have no clue on how to make them all work together

99% of the time you can use

depth = -y;

I have no idea what you guys are talking about since usually I see parallax as an entirely horizontal phenomenon... why you y'ing?

This is what I am making. I don't want the characters overlapping that's it.

oh, that's not parallax (or if it is it's not a typical usage of the word).

Parallax is when in side-scrolling sections the different background layers scroll at different speeds (such as really slow scrolling mountains)


Ya, for depth-layering you should be ok with something as simple as depth=-y, but make sure to calculate it based on where your feet are, not where your model's center is (IE: A floating ghost would have a value quite a bit below him)

[The Winter Bud]

//start of game event
globalvar MINIMUM_DEPTH=-100;
// NOTE-you can use a macro instead if you like
// since MINIMUM_DEPTH is a constant

//player create event 
depth=MINIMUM_DEPTH;

//enemy end step
var plyr=instance_nearest(x,y,obj_player);
if(plyr!=noone){
  depth=MINIMUM_DEPTH+point_distance(x,y,plyr.x,plyr.y);
}

this form of depth handling radiates around a center instead of a vertical plane like
depth=-y;

the closer the enemy is to the player, no matter it's direction is to the player, the more it draws the enemy on top of things.

EDIT: since the player's depth is at MINIMUM_DEPTH, he will always draw on top of the enemies.

Yeah I am an idiot, I just put depth=-y in the step event for every object and everything works. Thanks guys!
