Scaling up the damage buleprint to 5 solved my problem.
Crosshair aim patch (link is broken) I suggest that aim should be simple so the player can have easy fast action
1- The Crosshair follows the mouse pointer on screen freely.
2- When the Crosshair goes opposite the direction the player walk the character changes direction also.
3- When the Crosshair passes by an enemy or hit area it locks on for a second or more if the player shoots it stays locked if not it releases the target.
4- There should be editable variables for the developer so he can control the options like: -Lock on Target (check box) -Lock on Time (number in seconds) - Mouse Axis Invert aiming
5- The same should be done to the depth aim when clicking right mouse button.
That should enhance the quality of the kit. Another BIG THANKS.
