destroying enemies

[tailsko]

i am trying to create a sonic like game and can't seem to get my character to destroy enemies when it jumps on them, jump again when an enimy is destroyed, and lose life when the character is ran into by the enemy, any ideas?

What form of platform movement are you using? A custom movement, or the Platform Movement Object? It won't work with the default Platform movement.

You're going to need to use an invisible detector at their feet, and use that for detecting the collision with the enemy when you hop on them. For bouncing on the enemy, just use the jump event you'd use with your movement, only have it occur when the detector collides with an enemy, as opposed to pressing the jump button. For multiple hits before the enemy is destroyed, just subtract from an alt value of the enemy each time you bounce on them, and when the alt value reaches zero, destroy the enemy.

Since you're using a detector at the feet for testing collision when hopping on top of the enemy, you can just test for the player colliding with the enemy while the detector is not overlapping the enemy, then kill the player.

For a Sonic-like game a detector is not necessary. Sonic becomes a ball when he jumps, so you just say:
animation 'ball' is playing + overlapping enemy -> destroy enemy
In this case you need to change the animation to 'ball' [or call it whatever you like] when your character jumps.

As for the jumping up again, as Shawn said, that depends on the kind of movement you are using.

Ah yeah you're correct raven. A simple test for the ball animation is all you'd need. Not sure why I didn't think of that, considering I've played Sonic quite a bit back in the day lol.

You still need to do additional checks or use a detector, since the ball should only hurt an enemy from above. If you just check for the "ball" animation to overlap, then the player can hurt enemies from below.

That is true in sonic games though.
