I want to create in my game a model that when I touch it disappear you need to find 5 of these items to go to the next level how would I program this ?
I know how to make the object disappear what I want is that I have a 5 written on top near the score and every time I touch one of the 5 models in the level it disappears then on top it says 4 instead of 5 then 3,2,1 and 0 and I go to the next level.
p.s. it has to be the same model not different models.

Also I don't know if anyone knows but I would like a code of touching an object and it gives me information for instance I touch something and it says the sky is blue, then if I touch it again it says the sky is green.
I know how to code an object that when you touch it it says something but not that if you touch it again it says something completely different.
any help would be appreciated.
