GetMinimapScreen(Entity)
Returns an instance of MinimapScreen for the given terrain entity. In your class override this method and return the instance of your minimap screen. May be it's a good idea to attach a screen to the terrain entity and return it here.
Declaration
public abstract IMinimapScreen GetMinimapScreen(Entity terrainEntity)Parameters
| Type | Name | Description |
|---|---|---|
| Entity | terrainEntity | terrain entity to find a minimap screen for |
Returns
| Type | Description |
|---|---|
| IMinimapScreen | instance of minimap screen for given terrain entity if found |
OnCreateForCompiler()
Declaration
protected override void OnCreateForCompiler()Overrides
OnUpdate()
Implement OnUpdate() to perform the major work of this system.
Declaration
protected override void OnUpdate()Overrides
Remarks
By default, the system invokes `OnUpdate()` once every frame on the main thread. To skip OnUpdate if all of the system's [EntityQueries] are empty, use the [RequireMatchingQueriesForUpdateAttribute]. To limit when OnUpdate is invoked, you can specify components that must exist, or queries that match specific Entities. To do this, call Unity.Entities.ComponentSystemBase.RequireForUpdate<T>() or Unity.Entities.ComponentSystemBase.RequireForUpdate(Unity.Entities.EntityQuery) in the system's OnCreate method. For more information, see [ShouldRunSystem].
The [Entities.ForEach] and [Job.WithCode] constructions provide convenient mechanisms for defining jobs. You can also instantiate and schedule an Unity.Entities.IJobChunk instance; you can use the [C# Job System] or you can perform work on the main thread. If you call Unity.Entities.EntityManager methods that perform structural changes on the main thread, be sure to arrange the system order to minimize the performance impact of the resulting [sync points].
UpdateMinimapScreen(Entity, CameraControllerTarget, HexTerrainSettings)
Updates the minimap screen with the current camera controller target and terrain settings.
Declaration

| Type | Name | Description |
|---|---|---|
| Entity | terrainEntity | terrain entity to update |
| CameraControllerTarget | target | camera controller to set data on screen from |
| HexTerrainSettings | terrainSettings | terrain settings to send to the minimap screen |
