Time for action — creating some explosions


  1. 1. To spawn an explosion, create an method called SpawnExplosion. The parameters will be the particle amount, and the center position of the explosion.

    Method SpawnExplosion:Int(c:Int, xp:Float, yp:Float)
    
  2. 2. Add a FOR loop from 1 to the amount of particles.

    For Local i:Int = 1 To c
    
  3. 3. Create a local object of the particle from the sprite atlas.

    Local explo:ftObject = eng.CreateImage(atlas, 0,112,16,16, xp, yp)
    
  4. 4. Scale and rotate it randomly.

    explo.SetScale(Rnd(3,15)/10)
    explo.SetAngle(Rnd(0,359))
    
  5. 5. Add a random spin and speed.

    explo.SetSpin(Rnd(-4,4))
    explo.SetSpeed(Rnd(1,2))
    
  6. 6. Reset the layer to layerFX and create an object timer with the ID tmObjRemove to remove the particle after a random time between 100 to 2000 milliseconds.

    explo.SetLayer(layerFX)
    eng.CreateObjTimer(explo, tmObjRemove, Rnd(100,2000))
    
  7. 7. Close the FOR loop and play the sndExplo sound.

    Next
    sndExplo.Play()
    
  8. 8. Close the method.

    Return 0
    End
