Disappear and appear function

Hi I am new to unity and I am trying to make several objects to disappear on a mouse click and reappear/reloaded after the level is finished. I have also tried to used the renderer false and true but to no help.

We need more info, the “renderer.enabled” set to true or false just do the trick… you said you tried that already, what was it doing??

btw, you don’t have to just turn off the renderer if you want it to stay “invisible” until the end of the level… you could “destroy” the whole game object, which will eliminate it entirely out of the scene. You could always call it back though when you need it
