[REQUEST] Draw HUD without affecting position

Well just to shed some light on what the title says.
I am would like to know how to draw the HUD onto the screen without the position of that sprite changing. say like the angle of view has changed, and then the HUD that was drawn is in a different part of the view.
I would like to know how to keep the HUD on one position.
Does anyone understand what I mean when I say this?

Please and thank you.

I believe he's asking for 2d. I'm guessing since he's mentioned rotating the view.

Code: [Select]

var dx, dy, dir, dist;
dx=view_xview[view_current]+view_wview[view_current]/2
dy=view_yview[view_current]+view_hview[view_current]/2

dir=point_direction(dx,dy,XVALUE,YVALUE)
dist=point_distance(dx,dy,XVALUE,YVALUE)

dx+=lengthdir_x(dist,dir-view_angle[view_current])
dy+=lengthdir_y(dist,dir-view_angle[view_current])
Now dx, and dy contain the X/YVALUE's adjusted to counter the current view being drawn's rotation.  Don't forget to draw your sprite/text/whatever with -view_angle[view_current] as it's angle.

Gah, its not exactly working..
I don't understaned what you're telling me to do :\

First of all, I put that code in the draw event of the HUD object I want.
Here is the code I am using:

Code: [Select]

draw_sprite_ext(sprite_index,image_index,view_xview+250,view_yview+20,1,1,view_angle[view_current],c_white,1)

var dx, dy, dir, dist;
dx=view_xview[view_current]+view_wview[view_current]/2
dy=view_yview[view_current]+view_hview[view_current]/2

dir=point_direction(dx,dy,250,20)
dist=point_distance(dx,dy,250,20)

dx+=lengthdir_x(dist,dir-view_angle[view_current])
dy+=lengthdir_y(dist,dir-view_angle[view_current])

>_<

You're supposed to use dx and dy as the coordinates for drawing your sprite afterwards, and the angle for the sprite is negative view_angle[view_current]

Code: [Select]

var dx, dy, dir, dist;
dx=view_xview[view_current]+view_wview[view_current]/2
dy=view_yview[view_current]+view_hview[view_current]/2

dir=point_direction(dx,dy,view_xview+250,view_yview+20)
dist=point_distance(dx,dy,view_xview+250,view_yview+20)

dx+=lengthdir_x(dist,dir-view_angle[view_current])
dy+=lengthdir_y(dist,dir-view_angle[view_current])

draw_sprite_ext(sprite_index,image_index,dx,dy,1,1,-view_angle[view_current],c_white,1)
