As in chopping bits off ?

The only way I can think of is to create a bitmap of the required size, paste the image (of the sprite) onto that, and then grab the required bits of the image and use that for the sprite.

Good news everyone! I really am THAT good...

Aside from trying to make sure you dont have a white screen around your guy to start with, the only real way is the way I suggested.

Either draw your image in a paint proggy that understands and handles alpha settings, or if your image is 32 bit, use the function below to fix the alpha after you've loaded it.

Just use it like this:



That will make white transparent.

correct me if im wrong, but i believe ya mean that ya dont have any see-thru bits on ya sprites and its appearing as a block?? to fix this do one of either of these two things:

1. use black as your background for all sprites because that is the default transparent colour

2. use the command SET IMAGE COLORKEY red,green,blue
where red green and blue would be used to pick the colour you want as transparent (ie 255,255,255 would be white)

hope thats what ya meant!

optic blast! megablast! have a blast!!

You can either try and set the colourkey to this white colour, or do it the way I suggested.

Then your image wasn't 32 bit. I've used this function again and again when I was fine tuning my pixel-perfect sprite collision routines.

Post a link to your image - or email it to me - and we'll work out how to get it loaded properly.

Hey iammesol, the easiest way to do it is make the background of the sprite BLACK. That's all I do. And then if you need to use any black in the actual sprite just use a very dark gray colour. simple enough

you have to set the sprite so it appears transparent after you change the white to black as said above.

to get the white to be transparent you would need to insert "set image colorkey 255,255,255" before you load the image, then the white is treated as transparent.

or you could keep using black as the transparent colour.

Either way works
