I think the Gamera library (viewtopic.php?f=5&t=12033) will do what you want most easily.

Neither method is particularly demanding at all. Use whichever allows you to write the nicest code.

Honestly, just use the HUMP library: https://www.love2d.org/wiki/HUMP

It will save you so much time and effort; getting camera transforms right can be a massive pain in the ass. In HUMP you just set the camera x,y and do camera:attach() / camera:detach() when drawing non-ui stuff.

You should post a .love where this can be observed/checked by someone - it sounds like you aren't using dt correctly, as bartbes suggested. When you vary things by time you should have a factor of dt in there. function love.update(dt) x = x + 7 * dt -- dt is the amount of time in seconds that has pa...

I'm assuming you're working from not knowing anything here, so check out these two libraries:

https://www.love2d.org/wiki/Quickie - Quick and easy, but limited
https://www.love2d.org/wiki/L%C3%B6ve_Frames - A bit more complicated, but seems to be the most mature GUI stuff for LÖVE

In your shader you need to make use of the alpha value in the colour input - otherwise drawing the block with varying alpha will have no effect.

You probably want:

function menu:update(dt) if self:checkHov(height/2 - 95, 1, dt) then self:play_b -- you've forgotten something! elseif self:checkHov(height/2 - 45, 2, dt) then love.event.quit() elseif self:checkHov(height/2 + 5, 3, dt) then self:vol_change(love.mouse.getX(), love.mouse.getY()) end end Maybe you di...

You found a solution whilst I was writing this, but I'll post it anyway for anyone who might be interested: It will be possible will Geometry, which I understand will be in 0.9.0, so if it's not urgent then I'd hold your horses on patching love yourself. You could hack it will a pixel effect, but th...

Interesting idea, but to win I have to pay attention to the right hand side, and ignore the left; I think this could only work with more integration between the two sides.

I came for the ease of getting something on the screen in no time, I stayed for the third party libraries and ridiculously accessible pixel effects.
