Shooting in Unreal Engine 4 / MP Top-Down
Hi folks!
In my first tutorial I showed how to setup joysticks for Top-Down games – Advanced Joystick in UE4 / Multiplayer Top-Down. Now we’ll integrate firing in this. I.e. when shifting stick for a half from its center, character is aiming, and shifting for a max, character is firing.
This post based on previous, please l take a look.
Inside TopDownController create new Float var – FireRate with 1.0 value. There is a custom event RotateNow, that sets a new value to FaceRotation.
In first, we’ll check a vector length( we did that in prevous post, 11b and 12a articles). If it less than 0.8, character doesn’t shoot, else we call FlowControl function – DoOnce. DoOnce executes ones and then blocks. To unblock, it must be re-calle through the Reset (more about DoOnce can be read here.)
After it we call another FlowControl – Sequence. Sequence performs a sequence of action, Then 0, Then1, Then2, Then3… In our case, Then 0 calls PrintString( instead of firing), Then 1 – Delay, that calls Reset in DoOnce. Delay’s duration equals to FireRate’s value.
Instead of shooting, we call PrintString with “FIRE!” text
To change the rate, change the value of a FireRate var.
