Game Kit: Laser System (C++)

Screenshots

Fully customizable Laser System

• Implemented in both C++ and Blueprint
• Beam and impact effects are created in Niagara and can be replaced
• Laser beams can reflect from mirror materials and act as triggers

How-To

Create a new trace channel for the laser

Configure the trace channel in the Collision panel

For the C++ package

Save the settings in DefaultEngine.ini

[/Script/Engine.CollisionProfile]
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel1,DefaultResponse=ECR_Block,bTraceType=True,bStaticObject=False,Name="LaserTrace")

Replace the value on line 16 of LaserEmitter.h

static ECollisionChannel ECC_LaserTrace = ECollisionChannel::ECC_GameTraceChannel1;

And that's it…

Add the BP_LaserEmitter actor to the scene and set its parameters as you like.
