Constrained killzone

B1984

hello,

I have a 306x8 actor that will be an obstacle/spike in my game. I only want the bottom 8px to destroy the player, the rest is non-lethal. I tried to constrain self.size.height/.9.8, but my main character is destroyed as soon as I spawn.

This is how it looks:

Game attributes:

Spike real

Spike attributes
Constrain attribute self.size/height/.9.8

Character attributes
rules
collision or overlap with actor spike
do= destroy


Any suggestions? Thanks in advance.

(self.position.y)+((self.size.height)/.9)

That's the actual formula I'm using from jamie's tutorial "Gamesalad Recipe 003". He only needed the top of an enemy's head as the safe zone for killing the enemy, but I want the the shaft of a spike to be safe and the tip be the destroy zone.

Thanks for any help.

EDIT: The correct answer was (self.position.y)-((self.size.height)/2)

Hahah! I figured it out. Such a great filling tinkering around all you want and not having to worry about constant crashes =D
