Hi. I'm new to Construct 2. I'm using the free edition. I'm making a top down game. Here is my problem: I have an enemy, a snowboard, and a snowboard print object. The enemy is riding on top of the snowboard. I wanted the snowboard to only go down vertical. So the snowboard must not move in any other direction. When the enemy crash into a tree or rock, I want to destroy the enemy, snowboard, and snowboard print. However, when I run the game, when the enemy crash the tree or rock, all enemies, snowboard prints, and some(not all for some reason) snowboards are destroyed. How do I only destroy the enemy, snowboard, and snowboard print that crash the tree or rock? Here is the capx file. dropbox.com/sh/a1dslqya9h42gy0/Ywg-eIHrtV Use WASD or the mouse to move around. The player do not shoot. Just move around.
