getSpriteRotationSpeed()

Purpose

Get a sprites rotation speed

Description

This is the amount that the sprite's rotation angle is changed by when updatesprites is called

Syntax

rotatespeed = getSpriteRotationSpeed( sprite )

rotatespeed = sprite.rotation_speed

Arguments

sprite handle of the created sprite

rotatespeed amount to add to the rotation angle of the sprite at each updatesprites call

Example

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 } )
maxrs = 240 // max rotation speed
accr = 1    // accelaration

loop
    clear()
    rs = getSpriteRotationSpeed( ship )
    if abs( rs ) > maxrs then
        accr = -accr
    endIf
    setSpriteRotationSpeed( ship, rs + accr )
    updateSprites()
    drawSprites()
    update()
