Still having trouble with 90-degree turns...

Java 2D
#1

I’ve managed to do a 180 degree flip using drawImage() but I can’t seem to get 90 degrees. If I draw a single Pacman with his mouth pointing, say left, can’t I use drawImage() to render that image with him pointing up, down, and right? Given that the sprite is 32x32:

drawImage(img, 0, 0, 32, 32, 32, 32, 0, 0, null) should turn a left-facing Pacman to a right-facing Pacman. I can’t figure out how to get an up/down facing Pacman, or is this not possible and the image is only flipped?

It’s not possible…
The drawImage() methods allow you to translate and scale the image (even do a bit of clipping with the xs1,ys1,xs2,ys2,xd1,yd1,xd2,yd2 version) but there is not rotation included…

You will need a second set of sprites for the vertical animation.

Oh, I think the other topic on mirroring an image confused me. I was under the impression you could get 90-degree rotation, but I guess it’s only 180. Still, two sets of sprites is better than four!

Thanks.

Bishop,

I am really sorry, since I guess I was the one who confused you with the mirroring thing.

I thought, back in the other thread, that you wanted to simply rotate left/right and up/down. Now I realise that what you want is a tad different, and more difficult.

Sorry for the misunderstanding…
