draw_sprite_part() need help

[NoFontNL]

I've read the manual, but I can't figure out how the function works.

I want to draw a sprite. 4 to the right and 4 down from the object his x and y position. But cut 4 from the bottom off. Can someone help me?

Post your code and an example of the result you want. From your description alone ("4 to the right and 4 down"), this is something draw_sprite() can already do, so I have no idea why you're even trying draw_sprite_part() to start with.

draw_sprite_part(sprite_index,image_index,0,0,sprite_width,sprite_height-4,x+4,y+4);

4 to the right, 4 down, but cut 4 pixels off on the bottom

draw_sprite_part(sprite_index,image_index,0,0,sprite_width,sprite_height-4,x+4,y+4);

4 to the right, 4 down, but cut 4 pixels off on the bottom

That's exactly how it's done. What's wrong with it?

This is the full code I'm using:

if(!place_meeting(x+1,y+1,par_couele)){
    draw_sprite(sprite_index,image_index,x+4,y+4);
} else if(!place_meeting(x+1,y,par_couele)) {
    draw_sprite_part(sprite_index,image_index,0,0,sprite_width,sprite_height-4,x+4,y+4);
} else if(!place_meeting(x,y+1,par_couele)) {
    draw_sprite_part(sprite_index,image_index,0,0,sprite_width-4,sprite_height,x+4,y+4);
}

And I get this as result:

I think you have an issue with blocks being not aligned properly with each other. But in any case, I don't think this is the right way to do it. Shadowing is usually mediated through something else that draws under or over everything, not by things casting shadows.

An easy alternative is to use a separate obj_shadows that does this in its Draw event:

with (par_couele) {
  if (!(place_meeting(x+1, y, par_couele) && place_meeting(x, y+1, par_couele))) {
    draw_sprite(sprite_index, image_index, x+4, y+4);
  }
}

A more effective scheme would involve painting shadows to a surface and drawing only the surface all the time, then repaint the surface only when there is movement in things that cast a shadow. However, the details of that will depend on your project, so I won't go into that for now.

It worked! Well, thank you very much! No more words needed.
