Project Notes

This sprite is intended for checking pen and touching-color blocks for alignment errors. In the squeak implementation, the sensor is offset from the pen: a mark at x,y is detected at x-1, y+1 Hit 'a' to test lower-left corner 'b' to test lower-right corner 'c' to test upper-left corner 'd' to test upper right corner The touching sensor is correct---it detects when it is right over the dot it is supposed to. The pen is off (or the background is). The background goes from (-240,-179) to (239,180) which seems a bit inconsistent. Java places pen correctly (same background range).
