I tried this:
but it is wrong although it compiled what do i do
1 2 3 | GreenfootImage art = new GreenfootImage(1,1); art.setColor(Color.BLUE); art.drawLine(prevx, prevy, presx, presy); |
The image you are trying to draw the line on is 1 pixel wide by 1 pixel high. At most you will change a point and you need more than one point to draw a line.
The upper left corner of a GreenfootImage has the coordinates (0/0).
@Kartoffelbrot, I was referring to line 1 in the code given above. The image being create (the one that is to be drawn on) is too small to draw a line on.
I know. I wasn't referring to your comment. I only wanted to help and maybe that was a problem, too.
