Turing - Blocking my dot using if whatdotcolor URGENT

[TuringMaster87]

What is it you are trying to achieve?
<Replace all the <> with your answers/code and remove the <>>
Hey guys i have an assignment due sunday night, and i need to block off my dot from going over the boundries. So i have 2 dots one blue and green. And i did if whatdotcolor to each of them with no luck. The boundries work for some sides but not all.

What is the problem you are having?
<Answer Here>
Cannot block off the boundries

You need to put the boundary detection where you update the x/y coordinates.

First, you need to check if the dot is moving left. Then you check if it is within the left boundary. if both are true, you then update the x coordinate.
If either are false, check if moving right and dot is within the right boundary. If those are true, update the x coord. Repeat for the y coordinates.

If you have to use whatdotcolor (i wouldn't reccommend it), then to check the left boundary for example, you need a for loop (for y: lowerBound .. upperBound) and check whatdotcolor (leftBound, y) if you get a hit, exit the loop. if you make it to the end of the loop, then you know the boundary is clear.
