I'm making a pickup system for my game, but my script isn't working. When i mover over the cube, it is destroyed but my money counter doesn't go up.
what's going on here?
To increment an integer counter variable by 1, you just need to call the ++ operator, like this:
The reason for the strange behaviour in your script is that although the ++ operator increments the variable, it actually returns a different value - the value of the variable before it was incremented.
This means your variable gets incremented, but because you are putting the returned value back into the same variable, it gets immediately replaced with its original value.
An example, for clarification:
If you want to increment a variable by a value other than 1, you can use the similar += operator?
Hope this helps clarify things!
In addition, there seems to be some confusion about which object does the counting, and displaying of the money sum. The script that detects the collection of the money & adding should be on your player, rather than on the money object. Make sure your money objects are tagged "Money", then place this script on your player:
Remember to make sure that:
So, the above script (which is placed on the player) detects if the player touches a "Money" object. This single script counts the money total, and is responsible for displaying the amount, and for destroying the money object.
The money objects themselves need no script attached at all.
To make things a bit cleaner I like to add a tag to the gameobjects that are acquirable, though it is optional. In the case that you'd like to avoid that simply take out the 'if' statement in the beginning of the second function.
