Projectiles and LineTrace

After modeling our weapon and vehicle, we are now working on making our weapons function. To begin this process we learned about projectiles and the LineTrace node

Using line trace

The LineTrace node allows me to perform a trace collision over certain objects and return the object back. The important parts about setting up the LineTrace are getting the WorldLocation, WorldRotation, and the ForwardVector.

The end result is a tracer that returns the collision back to the player. The next step was putting together a projectile. Putting in the projectile was fairly simple because I used a SpawnActor blueprint node.

My projectile

The main components that make up my projectile is a simple static mesh and a Projectile Movement. Using projectile movement allows me to set the distance, direction,  and rate my static mesh travels.

On the right side is a details panel. The details panel allows me to adjust the projectile anyway I see fit. I can adjust how far my projectile travels or how much gravity affects the projectile's air time.
