Time for action — create a comet


  1. 1. To create a comet, we need a new method called CreateComet. The parameters are the kind of comet, its position, the travel speed, and angle.

    Method CreateComet:ftObject(k:Int, xp:Float, yp:Float, speed:Float, speedAngle:Float)
    
  2. 2. Define a local ftObject called com.

    Local com:ftObject
    
  3. 3. Depending on the size of the comet, create the comet object from different locations of the sprite atlas. Also, set the radius depending on the size.

    If k = cmSmall Then
    com = eng.CreateImage(atlas, 0,32,16,16, xp, yp)
    com.SetRadius(4)
    Endif
    If k = cmMiddle Then
    com = eng.CreateImage(atlas, 32,0,32,32, xp, yp)
    com.SetRadius(12)
    Endif
    If k = cmLarge Then
    com = eng.CreateImage(atlas, 64,0,64,64, xp, yp)
    com.SetRadius(24)
    Endif
    
  4. 4. Now, set the speed and the angle that the comet will move at.

    com.SetSpeed(speed, speedAngle)
    
  5. 5. Next, we set a random starting angle and spinning speed.

    com.SetAngle(Rnd(0,359))
    com.SetSpin(Rnd(-4,4))
    
  6. 6. Store the comet size constant into the tag field...
