Cheat-Sheet

A lot of things are common between game engines. Here's how to do a bunch of common stuff.

Console Printing

Log.Info( "It worked!" ); Log.Warning( $"{playername} is an idiot!" ); Log.Error( "Error!" );

Debug Drawing

// draw text at position for 10 seconds DebugOverlay.Text( position, "Some Text!", Color.Yellow, 10.0f ); // draw a line DebugOverlay.Line( startPos, endPos ); // draw text on screen DebugOverlay.ScreenText( "Hello, debug text!\nSupports multiple lines" );

Spawning an Entity

ModelEntity model = new ModelEntity( "models/citizen/citizen.vmdl" ); model.Position = new Vector3( 0, 0, 100 );

Get Entity's Eye Position and Direction

Vector3 eyePos = Entity.EyePos; Vector3 eyeDir = Entity.EyeRot.Forward;

Do a ray trace

// trace 2000 units in eye direction, ignore all entities TraceResult tr = Trace.Ray( EyePosition, EyePosition + EyeRotation.Forward * 2000 ) .WorldOnly() .Run(); // If we hit, draw a 2 inch sphere for 10 seconds if ( tr.Hit ) { DebugOverlay.Sphere( tr.EndPosition, 2.0f, Color.Red, duration: 10.0f ); }

Create a Server Console Command

[ConCmd.Server( "my_command" )] public static void MyConsoleCommand() { // the client that is calling the console command var callingClient = ConsoleSystem.Caller; }

Create a Client Console Command

[ConCmd.Client( "my_command" )] public static void MyConsoleCommand() { }

Console Command Arguments

// my_command Poop 7 false [ConCmd.Client( "my_command" )] public static void MyConsoleCommand( string one, int two, bool three ) { }

Calling a Console Command

MyConsoleCommand( "poop", 7, false );
