Please I want to ask some blueprint question

First I know how to do shooting a bullet, and if my bullet hit the target, how to stick the bullet to the target’s body and dont disapper?

question 2 : How to I make a bullet if I press the mouse left key for maybe 3secs, and the shooting power will better for the shooting. If I press the the mouse left key for maybe 1secs, and the shooting power will be less?

thank you so much.

Here is a Youtube tutorial series for using a Bow and Arrow, including having the arrow sticking in the target’s body. Could easily change the arrow for a bullet, although you wouldnt see the bullet stick to someone as it would be inside them
