Question

I wanna to implement an effect similiar to that which happens when super Mario eats the mushroom and grows. Should happen when a sprite collides with the main sprite. How can I achieve this in an easy way with the AndEngine ?

Answer 1

Register to your “Mario” sprite SclaeAtModifier:

final Sprite entity= new Strite(x, y, textureRegion);
final ScaleAtModifier entityModifier = new ScaleAtModifier(10 /*Durarion*/, 1/*from*/, 2/*to*/, 0/*scale center X*/, 0 /*scale center Y*/);

// register modifier
entity.registerEntityModifier(entityModifier); 

If your need not linear scale modification add specific IEaseFunction to ScaleAtModifier
