Add sprite collision effects

Add Collision effects to Sprites

Two sprites must have the same level to collide.

1. Select the sprite.

2. Right click and choose Properties.

3. Click on the Sounds and Collisions tab.

4. In the area Object Collision level, specify the Collision level of this sprite.

5. Click to specify if the path of the sprite must change after a collision with another sprite occurs.

• If you choose Change path, the object's path changes after a collision. This case respects the physics rules.

• If you choose Keep path, the object keep the same path after the collision. This case doesn't respect the physics rules and may accelerate small objects after a few moments of animation.

Two sprites must have the Same level to collide. Choose level 0 if you don't want this sprite to collide with other sprites. The collision is elastic. It means that it preserves kinetic energy, which is based on speed and mass of each sprite. It acts like 2 balls colliding on a pool table. In our model, the "mass" of a sprite is proportional to its size.
