I want to have a transparency as PNG do, you know with different alpha-stages. Look here:



How's that possible in GM5.3a?

That was my idea too, but I'm sure he didn't post it here, and ZFGC.org is down... I just remembered though that this forum is up, maybe he posted there.
Edit: Nevermind, I found it on his forums. *locked*

And if you need help with PS, feel free to ask, I'll leave the topic open then... (Good job, in before the lock, Tabbeth. XDDDD )

I think that example is for GM6.. if you want it for GM5.3, use the function draw_sprite_alpha(). It's just like draw_sprite_ext() except with 2 alpha arguments instead of 1: The alpha sprite, and the subimage thereof. :P

when I make shadows I use this code with a normal light type sprite (white to black).
Code: [Select]
draw_set_blend_mode(bm_subtract) //subtract kind of inverts the light
draw_sprite_ext(spr_light,-1,x,y,1,1,0,c_white,1)
draw_set_blend_mode(bm_normal) //set to normal blend mode
