Download "Racing AI Example"(8 sprites and 23 scripts) and open it in Scratch Project Notes
A test project in response to freddie-few's question in the forum about computer AI for race cars. This is a simple example where the car just follows a chain of waypoints that move back and forth. If you use more waypoints (at corners), it will look more realistic. The greater the waypoint movement, the more spastic the AI driver is.

Looby: That's a bug. The actual driving I game I made took care of that problem and simplified the movement of the waypoints (this version uses trig functions, which is overkill).

Have you noticed that the waypoints always move closer towards the center after a while? The car began driving on grass...

Great ideas in this project. I may remix some of it for my own racing game.

Note that I used trig functions to make the waypoints go back and forth smoothly, but that takes a lot of processor time, so I think it is much easier to use the glide block and just go back and forth.

bla: that's another good way to do it.

I edited it really quick.. It may be a little buggy. (link to project) sorry... I was going fast and didn't know how to make the sprite turn correctly while driving... so I used the old marble racer sprite

I'll try and mod it. I won't try and add more levels yet, until I understand how this actually works. :)

Note that the movement of the waypoint circles is very simple, and just uses one trig function to make it go back and forth smoothly. The same movement would be very useful in tgames you are making.

Very nice....now I'm starting to get a little motion sick from watching the waypoints go back. and forth. and back...Seriously though, a very simple and elegant solution. I was starting down Jens' path when you came up with this beauty.

Brilliant! I didn't even think of (simple) waypoints to accomplish AI when reading the forum question, since I was so preoccupied about letting sprite-robots 'sense' their way around checking for overlapping colors and adjusting their direction accordingly that the more elegant solution didn't even occur to me. Cool! Now, could you make some more levels, please !

Awesome, and a very quick response to the forum question. I imagined waypoints that changed each level, or each lap, but the waypoints in motion idea is even better...

Another thing that could be improved, right now it only heads toward the next waypoint when it hits the previous waypoint. It would be smoother if it switches waypoints when Distance to [waypoint] is less than some number.

Before Paddle2See asks me for more levels, perhaps someone can mod the project to add a player race car...
