Rotating sprites

Questions
1

Is there a way I can rotate a sprite to face where I touched?

So my sprite rocket can fight enemies in 360 degrees.

Try this


function setup()
    tpos=vec2(WIDTH/2,HEIGHT/2)
    shippos=vec2(WIDTH/2,HEIGHT/2)
end

function draw()
    
    background(0)
    pushMatrix()
    translate(shippos.x,shippos.y)
    rotate(angleBetween(shippos,tpos))
    spriteMode(CENTER)
    sprite("Space Art:Red Ship",0,0)
    popMatrix()
    -- do the rest of your drawing here
end

function touched(touch)
    tpos=vec2(touch.x,touch.y)
end

function angleBetween(ptA,ptB)
    local angle=math.deg(math.atan2(ptA.y-ptB.y,ptA.x-ptB.x))
    angle = angle + 90
    return angle
end

Great! Thanks @Coder

@Coder Instead of hand-coding an angleBetween function (using trigonometry), you can just use vec2.angleBetween.

rotate(shippos:angleBetween(tpos))

I thought that got the angle between two directional vectors but you could have vec2(0,1):angleBetween(tpos) but that would only work if the ship was a the origin (you could use translate)
