Hi,
normally you need to do this :
"Get FSM Int" then "Int Add" then "Set Fsm Int"
But there are actions on the
Ecosystem that can do that at once
look for 'Add to Fsm Int'
You can use this directly to the receivedCoin
or to the currentCoins depending on your needs.
then send the event.
or maybe you could use "int changed" on the CurrentCoins and use "Set Fsm int" on the currentCoins it will then trigger the int changed and you can do you currentCoins + receivedCoin. after that you need to set the value from currentCoins back to zero. then you can go back to the state with the "int changed" action.
You might need to use a next frame event before going back to that state after setting to zero.
This way there is no send event needed.
