Released
An open-source, community-driven successor to GMod's Sandbox. Work in progress!
Weapons/PhysGun/Physgun.Hud.cs
UI code for the Physgun weapon HUD. It draws a cyan circle at the crosshair; smaller solid circle when the weapon has a valid state, larger faint circle when hovering a valid target.
using Sandbox.Rendering;
public partial class Physgun : ScreenWeapon
{
public override void DrawHud( HudPainter painter, Vector2 crosshair )
{
if ( _state.IsValid() )
return;
if ( _stateHovered.IsValid() )
{
painter.DrawCircle( crosshair, 3, Color.Cyan );
}
else
{
painter.DrawCircle( crosshair, 5, Color.Cyan.WithAlpha( 0.2f ) );
}
}
}
