UE4 Weapon Projectile Blueprint

     This is my weapon research assignment from game programming class. In this assignment, I created the homing projectiles that follows the box target. Also, I studied Line Trace, Projectile Movement, and Physics.

     Line Trace is the laser pointer that allows players to aim physically in space instead of showing aim point with an image file. Projectile Movement is one of the important elements of the first-person shooting game that allows people to change the characteristic of the weapon (or projectile.) Physics allows people to control the impact of projectiles or change condition of the space.

       In level blueprint, the only thing that I added is to spawn another box target in case the box target is going off the map or is not functional. Collision trigger box is for hidden event.

      This is my projectile that goes to my target box. I added homing target component to make the projectile able to follow the target, Event hit for explosion effects and radial force, projectile bounce for making print string.

     This is my target box and also re-spawn mesh. The only thing that I used in blueprint is set simulate physics and detachfromcomponent to make it destructible.
