Target detectors

To add a target detector component to an existing object, go to Component->Physics->FluXY->Target Providers->Target Detector.

Target detectors allow you to dynamically pick up targets which should be splatted onto any given container. This enables targets to enter/exit different containers at runtime.

If targets are more or less tied to a specific container in your use case, specifying them in the container's targets list is a better choice since it has zero runtime cost.

Detectors find all target colliders within a rectangular area and splat them onto the container. This means targets can enter/exit containers dynamically. The detection area is drawn as a wire cube gizmo around the container (only visible if gizmo rendering is enabled in the Scene View window):

For a target to be detected, it has to have a Collider component.

Let's go over the detector properties:

Size

Size of the detector's area in the X, Y and Z axis.

Max Targets

Maximum amount of targets that can simulatenously be within the detector's area. Using a fixed amount of maximum targets prevents any garbage generation at runtime.

Layers

Only targets in these layers will be detected and splatted onto containers.
