[游戏开发]unity-ECS-DOTS笔记

Entity

Component

System

• Unity DOTS：深入浅出 SystemBase

Job

• C#虽然支持Thread，但是在Unity中只能处理数据，例如：网络消息、下载。如果想在Thread中调用Unity的API那是不行的。
• job中使用主线程API会报错：“UnityException: GetKeyInt can only be called from the main thread.”

		protected override JobHandle OnUpdate(JobHandle inputDeps)
        {
            Entities.ForEach((ref Move_Component moveComponent, in Input_Component inputComponent) =>
            {
                moveComponent.direction = 0;
                moveComponent.direction += Input.GetKey(inputComponent.upKey) ? 1 : 0;
                moveComponent.direction -= Input.GetKey(inputComponent.downKey) ? 1 : 0;
            }).Schedule(inputDeps);
            return default;
        }

应改为：

        protected override JobHandle OnUpdate(JobHandle inputDeps)
        {
            Entities.ForEach((ref Move_Component moveComponent, in Input_Component inputComponent) =>
            {
                moveComponent.direction = 0;
                moveComponent.direction += Input.GetKey(inputComponent.upKey) ? 1 : 0;
                moveComponent.direction -= Input.GetKey(inputComponent.downKey) ? 1 : 0;
            }).Run();
            return default;
        }
