Examples

For this example to work, the variable f must have been previously loaded with a Sphere Font object. Place this in the renderscript of a map using the Sphere IDE map editor.

f.drawText(0, 0, "layer width (0) = " + GetLayerWidth(0));

This will show the width of the bottom layer of the map in the top-left corner of the screen.

Notes

• The valid range of layers that this function will accept is between 0 (inclusive) and GetNumLayers() (exclusive).

• The number returned by this function is the width of the currently loaded map in tiles, not pixels. To return the pixel width, find the pixel width of a single tile image and multiply it by the number returned by GetLayerWidth.

• This function will only work while the map engine is running.
