So, I have started making a game for the TI-84+ and its called Plinko, which is played on The Price Is Right. I was wondering how I would go about keeping the board up on the screen and changing the "puck". I have the logic but when I draw a circle simulating the "drop" the previous puck locations are still on the board. Can anyone help me fix it?

I'm assuming you're using circle(x,y,r)? I recommend getting familiar with Basic Libraries, such as this function, like those found in Doors CS 7. With those, you'll be able to use a sprite and the library will do all the work: drawing, erasing the sprite when it moves.

Well I'm trying to do it with out the help Doors CS 7.

What I suggest doing is drawing the board, using stopic to store it, then every time the puck moves clear the screen, recall the pic and then draw the new puck location, while this seems like more work than just erasing the puck in the long run it will be quicker and allow you to expand the method to work in other scenarios.

You can find my implementation of Plinko here

It was written long ago but is rather optimized and should be a good place to look for inspiration. If you have any questions please don't hesitate to ask.

Actually, does Circle( support 0 like Line( does? I've never tested.


Code:

Well i tried that and it took forever to recall the pic. I don't seem to understand your code but I'll look more into it later when I have time.
Thank you very much!

Why? If you have lots of routines available to make your program faster and smaller, why reinvent the wheel?

Comic: Unfortunately, it does not support erasing.

Odogollie: If you're convinced about not using any Doors CS functions, I would indeed go with TheStorm's implementation. Don't forget that you could draw the degree symbol with Text() for a quick small circle too. Also, I'm considering moving this topic to TI-BASIC.

Sometimes reinventing the wheel is the way to learn more And DoorsCS would just a dependency that could be avoided

If everyone followed that logic, then the thousands of hours and years of my life that I spent developing the shell would have been a complete waste of time.

Yes but, I quote " I prefer to reinevent the wheel, I prefer that nothing has control except what I do." (well close enough.) haha.
