can i change the floor's color by function? i have tried the function sim.setShapecolor, it can only change the object's color but floor.i hope changinng the color of the floor that robot passed by,so what function i can use?

You can add a drawing object with sim.addDrawingObject and fill with items via sim.addDrawingObjectItem as the robot passes around.

Check also what types of drawing objects you can add.

Have also a look at the demo model Models/robots/mobile/lumibot.ttm that does exactly what you want (but with a color gradient).

Cheers
