We can Achieve this with Timers and Signals, adding a code inside process or Physics process will have bad impact on the fps and we should do this when there is no any other options. For example to update the map, we can create a timer that emits every 1 second, and it updates the minimap instead of making the code inside process which will be called every frame.
