Just point your mouse in the direction you want the gun to shoot in. Click on the mortar to set it's target. Control the spread and speed of the gun by changing the variables. If you need to move the fish, gun, or the mortar, I enabled the draggable.
I just wanted to make it if anyone wanted to incorporate it in to their game or animation. If you want to use it, please ask me and say in the notes and credits part that it came from me. If you want to remix, you do not have to ask. -------------------------------------Edit------------------------------------------- I changed the enemy and added a few more changeable stats.
