Quick Start

Five minutes from "plugin enabled" to projectiles in your own level.

#Play the demo

1. In the Content Browser, open /MassProjectileSubsystem/Demo/Maps/L_MassProjectileDemo. Enable Settings → Show Plugin Content if you cannot see the folder.
2. Press Play.

Things to try:

• Shoot the range walls at a shallow angle. Hard surfaces (metal, concrete) ricochet, and soft ones (wood) are penetrated. Each hit leaves a hole decal, and through-shots leave one on both faces.
• Press Tab to the Shell. It is slow and heavy, so gravity drop and smoke are obvious.
• Press F, then type proj.Stats in the console (~ key) to see the active count and frame cost.

The demo is Blueprint-only. BP_DemoShooterPawn holds all the firing logic, and Tutorial 7 walks through it.

#Fire in your own level (no Blueprint)

Any level works. The subsystem exists in every game world.

1. Open your level and press Play.
2. Open the console (~) and type:

proj.Fire 10 3

That fires 10 rounds of type 0 (Rifle) from the camera with a 3° spread. Full syntax:

proj.Fire [count=1] [spreadDeg=3] [type=0] [speedCm=0]

type is an index into Replicated Types (0 = Rifle, 1 = Shell, 2 = Plasma with the shipped settings). speedCm = 0 uses the type's default speed.

If nothing appears, see Troubleshooting.

#Fire from a Blueprint in two nodes

In any Actor Blueprint (or the Level Blueprint):

1. Right-click → search Fire Projectiles (category Mass Projectiles).
2. Type Config: pick EC_Projectile_Rifle.
3. Fire Event: drag out → Make Projectile Fire Event. Set Origin to a world location, Direction to a unit vector (for example Get Actor Forward Vector), and Count to 1.
4. Call it from an input event or a timer.

The full version (camera aim, muzzle offset, automatic fire) is in Tutorial 7. For a networked weapon, use the component in Tutorial 8.
