Re: rotation question

Here you go, quick and dirty: function love.load() love.mouse.setVisible(false) lAngle = -90 dAngle = 0 end function love.draw() love.graphics.setColor(255, 255, 255, 255) love.graphics.ellipse("fill", mX, mY, 4, 4) love.graphics.ellipse("fill", 400, 200, 10, 10) love.graphics.se...

Re: rotation question

Does it rotate the 'long way round' when your mouse is any quadrant? Sounds to me like you just need to get the signs right depending upon which quadrant the cursor is in. If you look at the output of atan2 using something like this you'll see what's required: radius = 100 for i = 0, 359 do x = radi...

Re: rotation question

As I said before, atan2 will help you fix the issue - here's a good explanation: https://gamedev.stackexchange.com/quest ... f-a-vector

EDIT: I see what your diagram is driving at now, but the way to solve it is still with atan2

Re: "On the roof": my first platformer game

Did I use the word indulgent when I was 11? If you are and this is all your own work then well done on both counts. Because of the weird gravity, there's no clue as to how high and far you can jump which is a bit frustrating. You can also cling onto a wall by holding 'right' and 'up' but then have n...

Re: rotation question

Perhaps look into atan2 (https://love2d.org/wiki/General_math)? I think you can then work out which way is the shortest, rather than always going the long way round :D

Re: Ludum Dare 40

Aww, haven't entered since #36, want to jam but 25% of my weekend is already accounted for :( Ah well, maybe I can do a 60 hour jam instead :D I think some of the final themes are a bit naff - can't see 3,000 different games coming out of a theme like 'floating islands' - but some of them sound epic...

Re: FÖNTGen makes pretty fonts

Double-click to start does now work on my Linux box :D Two more little points... 1 Is it worth having numerical values change when mouse button is held down on triangle thingies? 2 I set a stroke value of 6 as a test and there's a gap between the character and the stroke: Screenshot at 2017-11-10 17...

Re: FÖNTGen makes pretty fonts

I've just noticed, you said:
... and you can even click on the numbers and edit them manually
Which is what I was suggesting but I don't see any numbers (maybe I'm just being dim as usual).
