[Solved] How do I add all the instance variable value of each instance for a single object?

I have a sprite called "Coins" and it has an instance variable of "CoinValue_IV". There are more than one instances of the same "Coins" sprite presents on the layout. Depending upon the "CoinValue_IV" of each instance, the user will get 100, 500, 1000 coins respectively.

So, my question is, How do I add all the instance variable value ("CoinValue_IV") of the "Coins" sprite?

Means, if the user will collect all the coins, total how many he will have on that particular stage.

I tried

"Coins.CoinValue_IV*Coins.Count"

on every tik, but it doest work.

Unfortunately, there is no such expression. You need to loop through all instances and sum up all values:

Global (or local) variable TotalAmount

For each Coins : Add Coins.CoinValue_IV to TotalAmount

Hi, thanks for your quick ersponce.

I tried that but sadly it doesn't work, the TotalAmount_GV does not stop adding numbers, I even added a triger once to it.

Don't add Trigger Once to loops.. If you need to calculate this total once, do it in On Start of the layout event.

It kept counting so I tot by putting "tiger once", it may stop but sadly no.

there are 10 coins present on the layout, for 8 of them, I made "100" to its CoinValue_IV, and remaining 2 "50" to its CoinValue_IV.

So the value of TotalAmount_GV should be 900. but its keep increasing.

Try this.
