Project Notes

Click the cat and move the mouse, left and right. The cat will copy your moves.

An array is a bunch of variables in one.
This "array" has 16 compartments it can store in.

When you click the cat, it sets these variables in order 1, 2, 3 ,4 ... to the x-mouse position. when it's done, it reads those back and moves to that order.

This "array" works like this:
First the set-value is set to to the x-mouse, then to store it in a certain compartment, say #1, the set-at is changed to 1.

When that set-at is changed from 0, it does the 'number guessing game' to determine what compartment (or variable) to set: Is it less then nine? yes. is it less then 5? yes. Is it less then 3? yes. Is it less then 2? yes. ok, then set variable 1 to set-value.
after it's done storing the number where it goes, it sets "set-at" back to 0 to wait for the next set.

The get method works about the same way.

I did this tree/guessing method to lower then number of steps needed to determine what variable to set or get.
so instead of 16 tests with a "flat" test, (Is it 1? no. Is it 2? no. Is it 3? no...) there's just four.

and it's expandable. (for 32 places only 5 tests are needed, for 64 only 6 tests are needed...) so that's when you should start to notice a performance gain over the flat method.

It's would just be a pain to expand this. I may use jen's chirp with xml export to do it. I just had trouble with the global variables changing back to local when imported back it... I'll have to build it another way. You're welcome to try. Or I'll save some hair and wait for arrays to be put in scratch. =(:-)
