I'm making a turn based strategy where the player can damage enemy, i wanted to display the damage that the enemy recieved when attacked by the player so that it shows how many damage the player gave to the enemy. i wanted the damage counter to fly upwards an decreases their opacity and then hides itself. is this possible?

Sorry if you didn't understand that much thanks!

You may want to look for a number display tutorial. It would usually advise you to use clones for digits, and you can script them to do the effect that you want.
