camera_set_zoom_block magnitude [time]

Zooms the camera in/out to the desired magnitude. Values larger than ‘1’ zoom the camera out while smaller values zoom in. These values are relative to the default zoom value of ‘1’, not the current value. As such, while using a value of ‘0.5’ would double the size of the graphics, running the same command again would result in no change. The zoom will happen over the given time period. Blocks until the command completes.

Zoom operations might not be as smooth as desired if the requested zoom level results in an edge of the camera meeting any defined camera limits.


  • magnitude: Magnitude of zoom

  • time: Number of seconds the transition should take, with a value of 0 meaning the zoom should happen instantly (default: 0)
