Angle visualiser thing

[BlackBulletIV]

Since I was getting confused as to where angles start in Love2D (FlashPunk starts on the opposite side to Love2D), I made this utility which shows the 0 degree point, and the direction angles travel in. It also shows the angle from the centre of the screen to the mouse.

So, for future reference: angles start on rightmost side of a circle, and travel clockwise.

I had lots of experience with clockwise angle system (Flash and it's programming language [AS 3.0] does use the video coordinate system, aka, those with Y values increasing downwards) .

Very useful, I've added to my "must have" list

Thank you!

Clockwise appears to be the norm. Flash and Love2D use it, but Flash, at least with FlashPunk, uses angles that at the left side of the circle. Also, Love2D uses the same coordinate system.

Very useful, I've added to my "must have" list

Thank you!

Glad you found it useful.

Aha, this could be useful to people like me who suck at maths!

Great work, appropriately titled

Oh! This reminds me a lot of the control system for FFIII on Android:

You mean that thumb stick thing at the bottom-left? I suppose they have some similarities.

Also, wow, it's been downloaded 77 times already. :O

Because it's clean, clear and very useful !


EDIT :

i suggest you replace this line
moveAngle = (moveAngle + math.pi * dt) % (math.pi * 2)
by this one
moveAngle = (moveAngle + dt) % (math.pi * 2)

and this one
love.graphics.print("Purple line is 0 degrees/radians\nRed line shows the direction angles move in (clockwise)\nHold shift to snap mouse to increments of 10 degrees", 5, 5)
by this one
love.graphics.print("Purple line is 0 degrees/radians\nRed line shows the direction angles move in (clockwise)\nHold shift to snap mouse to increments of "..snapDegrees.." degrees", 5, 5)

Good to know.

I've added a screenshot to the main post.
