You can use a shader. I gave an example here: viewtopic.php?f=3&t=85051&start=80#p219902

Ok, sorry for the late answer but I don't understand why I don't have the notifications... No worries. You only get notifications if you're quoted. I've quoted you now so you get one :) You can also subscribe to the thread if you want to receive notifications by email when someone posts, regardless...

Well, you can try to do tricks so that it more or less looks like physically accurate, which seems to be what you're trying to do. Or you can have something that more accurately resembles actual physics. Or you can use a physics engine (like love.physics, which uses Box2D internally) and let it hand...

Ah, I could see it by taking a snapshot. Thanks, ReFreezed. Indeed it looks like a rounding problem. That triangle is most likely the dividing line between the upper and the lower triangle of the quad (rectangles are drawn as two triangles). I guess the main problem is the 50% part of the 250%. Roun...

As for direct X, I literally lifted this from SDL because 'SDL 1.2 requires DirectX 7' ? I think I've just been overly cautious with the dx versions, because there isn't much info on this what what I've seen. I would clarify that DirectX is only required in Windows. As a Linux user, stating that it...

I can't see any glitch.

To clarify, I'm not the OP and I didn't write the game that was posted in the thread. I just posted this example: I know, I was replying to your post though. Oh, then I don't understand what you mean here: I just took a peek at the included resources. I suspect you're drawing lots of different imag...

Also don't forget getColor.

The similar performance with 0.10 and 11.0 in the example I posted suggests that either auto-batching is inactive by default, or that the bottleneck is something else (e.g. total amount of pixels changed/rewritten). I just took a peek at the included resources. I suspect you're drawing lots of diff...

or if you prefer to just convert the value to whole numbers again: function WHY(float) return math.floor(float*255) end I'd recommend this approach but adding rounding (just in case default rounding falls short of an integer by just a tiny bit during the conversions). function WHY(float) return mat...
