Sprite Fade

Blitz3D Forums/Blitz3D Programming/Sprite Fade

I've noticed if the center of a sprite is off the screen it appears faded or "alpha"

Is there a way to prevent this from happening?

Thanks!

I have never noticed that happening, and i don't think that is supposed to happen. Can you test this in a simple piece of code, where you just position the centre of a sprite off screen, and that'sit. Does it still happen?

I noticed that the other day when I was just messing around with code. I thought it was a lighting problem at first but now I think it is some kind of DX7 bug.. ? it even happens when I set the entityfx to full bright

I've noticed when other entities move into the sprite in just the right way, it also happens, not to sure.

I figured out what the problem was, thought I'd post this for future reference if anyone comes across a similar issue..

I had an alpha textured sprite on top of another alpha'd entity, for some reason the alpha textured sprite become "extra alpha'd" in certain areas

Yeah, the old 'alpha on top of alpha problem'.

I once had an alph'd river and alpha'd treeleaves in the same scene which caused the alpha'd river to visually 'punch' through the river bank.
Yuk - messy.

I took the alpha off the treeleaves and the problem ceased.

Also, with alpha'd trees the back leaves can often show through the front leaves.

One thing I would like for any B3D update would be proper alpha-sorting.
