making a compass problems with drawing

[janvos2506]

Hey so i have made a compass for my nxt so i now wich angles and stuff
i wrote some code to draw a circle and a line and that line keeps pointing the same way as you started it but i dont know how to refresh
i use this

Code: Select all

Graphics g = new Graphics()
                         g.drawLine(44,36,x,y)
                          g.clear()

and the x and y change the whole time but this code works but it isn't smooth the line disappears and appears randomly?
isn't there some sort of g.refresh() or something?

You will have to disable the autorefresh of the LCD. Then manually refresh after you draw and before you clear. Take a look at the LCD class for the appropriate methods to do that.
