Lose If The Character Didn't Jump Over A Specific Platform

i have a jumping / running character, i want it to lose if the character didn't jump over a specific platform or running without touching it, how can i do this?

 

please send a clear description of the problem

 

i want the character to lose if didn't touch specific platform or didn't take an action
for example there is 4 coins if player get only 3 he lose .. he must get 4
or : there is 4 cubes and the character jump over .. if he skip one he lose .. he must jump over 4 cubes

 

1. Place the action/platform
2. place an decoration object (with same or slight bigger collision shape) in the same place of that action/platform with the settings - opacity 0 and x/y velocity to 2000 or something and wake up by collision
3. attach an invisible enemy with the decoration object

when the character touches the decoration object, it will move with the invisible enemy and give access to character other wise the character will die.

Hope that will do

 

i will try it .. thanks
