3D Target Tracker and Direction Indicator for Godot 3.2
- Transfers parent 3d position to 2d screenspace and displays icon with direction arrow
- Useful for indicating the position of all kind of 3d game objects on the players screen
- Different modes to change behaviour and show target while onscreen, offscreen or always
- Offscreen mode for e.g. enemies behind the player, grenades that are thrown close under the feet
- Onscreen mode for e.g. to show worldmap locations and quest givers in front of the player
- Always mode for e.g. to track party members position or indicate important 3d audio effects for deaf players
- Ruby colors!
The example project comes with a minimalistic Demo_Scene that shows the intended Node setup. In the folder directory src/3d_helpers you find a 3d_Target_Tracker.tscn scene file. Add this 3d_Target_Tracker scene as a Child to any 3d Node you want to track ( must have a 3d transform / inherit from Spatial )
To make the direction arrow work correctly move the 3d_Target_Tracker node in 3d view to a position higher than the target node. Otherwise the arrow will point at the toe on the ground on a large monster instead of its head when it is close to the screen border. When the target is on screen the direction arrow will automatically switch to aim down at the targets ground position to avoid pointing in the wrong direction when the 2d positions overlap.
Use the nodes export variables in the inspector to adjust settings. Use the bool is_tracked variable to toggle the display on and off from code. e.g. to start the tracking only when an enemy turns aggressive towards the player

Script works without setting a bounding box for the parent model by using the center origin ( 0, 0 ) to decide if it is considered on screen or not which works fine for most 3d models.
If that doesn't work for your large scale model you might want to modify the script and work with a VisibilityNotifer and bounding box to solve this issue for your model. This solution is not provided with this examples.
