Rotating something over time or distance

General
1

Is there any easy way to rotate something (preferably a physics body) over timer or equally over distance? Example: a line rotating 90 equally over the time it takes for it to move across the screen. Something that would work like tween.rotate if it existed.

@Staples Something like this.


displayMode(FULLSCREEN)

function setup()
    r=0
    x=0
    stroke(255)
    strokeWidth(4)
end

function draw()
    background(40, 40, 50)
    translate(x,HEIGHT/2)
    rotate(r)
    line(0,-50,0,50)
    x=x+1  
    r=r+90/WIDTH
end

@Staples If you want to use a tween, here’s an example with a sprite.


displayMode(FULLSCREEN)

function setup()
    t = {x=0,y=HEIGHT/2,rot=0}
    tween(2,t, {x=WIDTH,y=HEIGHT/2,rot=360},
                {easing = tween.easing.linear,loop = tween.loop.pingpong})
end

function draw()
    background(40, 40, 50)
    pushMatrix()
    translate(t.x,t.y)
    rotate(t.rot)
    sprite("Planet Cute:Character Boy")
    popMatrix()    
end

@dave1707 thanks, works perfectly and a lot simpler than the long, hacky version in my head!
