Can anybody gimme some general tips about optimization that I can keep handy? 1) Fast algorithms: don't use an O(n^2) when there is an O(n log n) algorithm out there. 2) Spritebatches: the reduced draw calls improves performance greatly. 3) Don't use pairs() unless you must. 4) Use locals: this is ...

Given that .wav works, I'd suspect the VorbisDecoder. Have you tried logging a few samples from the SoundData? Compare some random sample on ARM to the same sample on x86. If the underlying samples are different, then it's probably the decoder. If they are the same, there is some other problem.

WP does support COM, including a subset of Win32 and Direct3D(9_3). Obviously, this what allowed T-Bone to use ANGLE (which implements OpenGL via Direct3D functions) to support Love. Secondly, it's not any slower than other ARM based platforms. Your compiled C++ code will be just as fast as on almos...

Very cool.

nit: Reduces parameter 'zero' should, for clarity, be called something like 'initial'. It is necessary for 'zero' to have a value other than 0 (for example: product) which must be why you have it as a parameter. That's a bit of unexpected value for 'zero', yea?

which is a heiti for sword (normally sverð).

Because in the situation that I need to use rects in, that's still slower. I wouldn't be asking for a pointbatch if I didn't know what I was talking about. OK then. What's the issue with a sprite batch of a 1x1 image with the width + height of the rectangle as scale? It works fine for many thousand...

Why not draw to a canvas and only redraw to the canvas when the GUI layout changes?

You can batch rectangles & lines really easily: add a 1x1 pixel image with the desired width/height/rotation to a spritebatch.

Also what's your current error? "Still doesn't work" is descriptive.

The file `mcgood (mcgoodsteak7).png` should be named `mcgood (mcgoodstreak7).png`. At least, that's what the code expects. After that I get no errors with your current main.lua.

The chunk you posted is perfectly valid. The error originates further up.

You need to call world.loadGraphics, where pauseButton is loaded, some time before the first time love.draw() is called. For example, this doesn't crash: function love.load() gravity = 30 platformBottom = love.graphics.getHeight() - ( love.graphics.getHeight() / 4 ) world.load() player.load() world....
