So in my game, I have a sign object. When the player gets close to it, it displays text. Simple.

My problem is with the depth. I want the text to be displayed on top of everything else, while the object's sprite in the world should be drawn behind most other objects. Here's my code:

Code:

depth = 100000
draw_sprite(sprite_index,image_index,x,y)
if collision_rectangle(x-8,y-8,x+16,y+16,ob_player,false,true){    
   depth = -100000
   draw_text_ext(view_xview[0]+8,view_yview[0]+170,text,10,300)
}

Instead of drawing the sign behind everything, though, it draws it in front of everything just like the text. No matter what order I put the two depth declarations in, it always seems to draw everything with the first one. Am I doing something wrong, or is this just how Game Maker works?

It's how GM works. An instance can only draw at one depth per draw event.

You'll have to use another object for displaying that stuff.

Ah, that's what I thought. I just made it so the player object draws the text (passing it from the sign), and everything works fine now

you can only change the depth in the step event, not the draw event. you can't change it in the draw event because the flow of a gm game is:

- go through every object's step event
- go through every object's draw event, in order of their depth

changing the depth in the draw event won't change the order that it's currently going through, because it'd make no sense.

Yeah, that makes sense now. I tend to get confused and do things ass-backwards when I've been working in GM too long.

Another stupid question that probabvly has an obvious answer:

I have an object that I want to rotate at a constant rate... Kind of like those rotating statues in Zelda that shoot at you.

Here's my create event:

Code:

dir = 0
//set a direction

Then I make it rotate in the step event:

Code:

dir +=1

The problem is where I try to find its line of sight. Here's my collision code (also in the step event):

Code:

if collision_line(x,y,lengthdir_x(40,dir),lengthdir_y(40,dir),ob_player,true,true)&&guntimer <= 0{
   i=instance_create(x,y,ob_pl_shot_missile)
   i.dir = point_direction(x,y,ob_player.x,ob_player.y)
   i.hspd = lengthdir_x(5,i.dir)
   i.vspd = lengthdir_y(5,i.dir)
   guntimer = 20
}

That creates a missile, but it goes in the wrong direction. To test my line of sight, I decided to draw it:

Code:

draw_line(x,y,lengthdir_x(40,dir),lengthdir_y(40,dir))

And sure enough, the line doesn't just rotate slowly, it waves back and forth in a right sinewave pattern.

I checked the "dir" variable, and it's adding one each steo like I told it to. So I guess I'm doing something wrong in the "lengthdir" functions. Anyone know what I'm doing wrong?

Anyone know what I'm doing wrong?

Yes, it's a simple mistake, but actually took me far longer than it should have to pick up. 

It's

Code:

draw_line(x,y,x+lengthdir_x(40,dir),y+lengthdir_y(40,dir))

Thank you! 

I knew it would be something simple like that.
