Hi guys!
I want to do something unusual , at least for me,

Basically, i have this :

1  
2  
3  
4  
5  
6  
batchPlayer.setProjectionMatrix(camera.combined);
        batchPlayer.begin();
        worldUpdate.updateAndRenderArrows(batchPlayer);
        worldUpdate.updateAndRenderEnemies(batchPlayer);
        player.draw(batchPlayer);
        batchPlayer.end();


How should i make it in a way, so i can draw the transparency of the images in red for example? or pink?

is there any method in SpriteBatch?

A quick solution I can think of would be that you just draw a square of the desired colour behind the Sprite. Not very efficient but I guess it would do the trick for "debugging purposes"

Call player.setColor(r, g, b, a). Would that do it for you?
