libgdx sprite fade out
fadeout, libgdx, sprite
Solution
You should be able to fade out your dead enemy sprites by decreasing their "alpha" over time. I think the easiest way to do that is to use batch `setColor()`:
batch.setColor(1.0f, 1.0f, 1.0f, fadeTimeAlpha);
batch.draw(deadEnemySprite, ...);
You'll have to compute the `fadeTimeAlpha` (taking it from 1.0f to 0.0f over time). The `Color.lerp()` methods might help.
I'm not sure if setting the color for each sprite will cause the batch to flush (I suspect it will), so this might have a relatively high performance cost (assuming your batch sprite drawing was behaving well beforehand).
Problem
I'm working on 2D shooting game in LibGdx. I have to mention that I'm new to LibGdx, and I'm trying really hard to understand how it works. I have experience in Java and Android programming for few years, so I understand game concepts. I'm interested is there a way to fade out sprite object. I have enemies on screen, and when enemy is dead I want to remove Enemy object from my list and ignore it inside calculations and intersection logic. But I want to enemy's sprite stay on the screen for a bit longer and to fade out slowly. Is there a nice way in LibGdx to handle this...or I have to draw some extra "fade out" frames...and to handle it inside animation... Is there a built in feature that supports this kind of stuff? Tnx a lot! I need someone to clear that up for me, before I begin to brain storm, and lose lifetime in drawing sprites.
