Adding the compass

BPC_Compass is the per-player brain of the system. It builds the compass HUD, handles the marking inputs and keeps every marker updated on screen. The HUD is created for you; you don't add any widget to the viewport yourself.

Requirements

The component must sit on a Pawn or Character, not on a PlayerController or PlayerState. The pawn needs a Camera Component, because marks are traced forward from the camera. The HUD is only shown to the player who controls that pawn.

BPC_Compass settings

Select the component in your character Blueprint to see these values in the Details panel.

Setting	Default	What it does
Mark Range	10000000	How far a player can mark, in centimeters. The default equals 100 km, which is effectively unlimited.
Remove Mark Threshold	200	If a player marks again closer than this distance (cm) to their existing mark, the mark is removed instead of a new one being placed. Default is 2 m.
Max Number Of Danger Markers	3	The most temporary marks (Danger and Item) one player can have at once. When the cap is reached, the oldest one is removed.
Add Player Marker	true	When on, a Player marker is attached to this pawn so teammates can see the player on their compass.
Update Interval	0.01	How often (seconds) marker positions refresh on screen. Lower is smoother, higher is cheaper.
Project Setting	DA_ProjectSetting	The data asset that defines every marker type's look and the player colors. Usually leave it; if you want different setups (say, per game mode), duplicate it and assign the copy here.
Unknown Item Data	Item · 15 s	The look of an Item ping placed on something without BPC_AutoMarker (key 3 or the menu's Item option). It uses the same marker settings.
Single Click	false	Not connected to the marking logic in this version, so changing it has no effect. Leave it at the default.
Marker Spawn Data		Internal value filled in when a mark is created. Don't edit it.
