Can some one show me a code exampel a jumping cone and when you walk and tuch it you have to start all over again.. And if you jump on it kill it?? Simple 3rd person

you should look at the sliding collision examples in the help files. What you would want in this case is if there was x or z collision (the sides) you would die, and if there was y collision, you kill it. To make it jump assign it the gravity like in the tutorial.
