setSpriteRotationSpeed()

Purpose

Set a sprites rotation speed

Description

Set a sprites speed of rotation. This is the amount that the sprite rotation angle is changed by when updatesprites is called

Syntax

setSpriteRotationSpeed( sprite, rotationSpeed )

sprite.rotation_speed = rotationSpeed

Arguments

sprite handle of the created sprite

*rotationSpeedamount to add to the rotation angle of the sprite at each updatesprites call

Example

radians( true )
image = loadImage( "Untied Games/Enemy small top C", false )
ship = createSprite()
setSpriteImage( ship, image )
lastpos = { gWidth() / 2, gHeight() / 2 }
setSpriteLocation( ship, lastpos )
setSpriteScale( ship, { 10, 10 } )
rv = 0
maxrv = 30 // max rotation speed
accrv = 0.3 // accelaration

loop
    clear()
    c = controls( 0 )
    printAt( 0, 0, "Use left joystick left or right to change rotation speed" )
    rv = rv + c.lx * accrv
    if abs( rv ) > maxrv then
        rv = rv / abs( rv ) * maxrv
    endIf
    setSpriteRotationSpeed( ship, rv )
    updateSprites()
    drawSprites()
    update()
repeat
