Practical example for a memory leak: Have a textbox, have it have a zoom in/out function. We reload our font with Font = love.graphics.newFont( zoom) _Font_ is overwriten each time so logically we would assume the old font data is discardet as it is no longer referenced. This is not the case because...

Somewhere in this player:draw mess you call either translate or scale which of course makes all following positions incorrect.

Thats a broad question and largely depends on what type of game, how many objects are on the screen or even how many pixels the game has. Losely there are 3 approaches to this: Mapping based - Where the entire viewable area is mapped to a table, that means around 10-100 pixel are grouped together as...

Oh wow thanks for finding these, so i tried them on the 10mb file and it gave a 40% reduction to 6mb. But THEN i tried them on a file where i already added an alpha layer and did the cutout and the reduction was over 60%. I can live with that. I also found another stupid method: just save the file a...

Yes knorke i know how masks work and they are in consideration, i just dont like using them for this tasks.

I just tried optipng, that sounded promising, i was looking for exatly that, BUT it only reduced the 10.8mb file to a lousy 10.4mb which is even worse than having gimp do it.
