Transparent sprites in GM8

[9robin3]

Hi! I noticed that you don't make sprites TRANSPARENT the same way in Game Maker 8 as in earlier versions.

How do you make transparent sprites in GM8?

 

[Agckuu Coceg]

1) Sprite > EDIT SPRITE > EDIT > SET TRANSPARENCY BACKGROUND

2) Sprite Editor » Image Editor » Image (menu) » Erase a color...

3) Sprite Editor » Image Editor » Change all pixels of same color [H], set the Opacity (right toolbox) to 0, and Blend Mode to Replace. Then click the color that is meant to be transparent.

I wish I'd read this post earlier, that's really useful.

Something from GM7 that I had trouble with till I realised is transparency for sprites takes the bottom right pixel only and uses that as the transparent background colour (provided the image is set to be transparent). A simple thing to do is expand your image by 1 pixel in either direction and fill that line in with your transparent colour if you find yourself using the bottom right pixel for your sprite.
