Random maze movement

MrEsch

Hello

I have been developing a Pacman game for my students to look at. The key concepts are about how sprites can deal with wall collisions and getting sprites to randomly move around a maze.

Here is my game so far http://scratch.mit.edu/projects/10181896/

I was wondering whether anyone would be able to help me with the following things:

1. The pacman struggled to get around the maze - anyone managed to script anything which allows smooth movement within the maze?
2, I want to get ghosts moving around mazes better.

I would really like some simple concepts which could be shared with young Scratch programmers, whereby they can check out the code and develop it further. Would anyone be interested in making a quick game to demonstrate this?

Thanks in anticipation!

Check out this project.

However, this doesn't quite work, as it's not random and Blinky can only sense where there's a dead end. It can't detect if there's an opening to the left or right unless the path ends. Here's how I would (and probably will) do it: (also noted here)
1. Make a sensor sprite for each of the ghosts and Pacman.
2. Have the sensor sprites detect how many openings there are
3. Make a script so that based on the number of openings there are, a certain thing would happen.

Hope this helps!

Interesting. I have made a random turn, so that it will turn if it hits a wall. I am still not sure how to get it to detect an opening.

YouTube is usually my friend, but there doesn't appear to be much out there on this topic! I have been told that making your stage more of a grid would help, but not quite sure how to achieve this.

I also tried to make a pacman game.
But i've never finished it because there were some problems
i could not handle so i didn't upload it, but if you want to look at it
i can upload it for you.

Movement of pacman works well but the ghost AI got brocken somehow.

Btw you can hide the variables so you can see the whole screen if you want. Just go to the variables tab and uncheck the box next to the variables you want to hide.

Maybe the way to solve it is using sensor sprites with the ghost effect at 100 (so they are not seen):

Thanks for advice, I had them shown when I was programming it - just forgot to hide it!

I will take a look at the ghost idea in the next few weeks and see what happens…watch this space!

It seems there is a better way to do it: RAYCASTING:

I just read it…I just would not know where to start with that!!

The problem with the pacman script is that you have too many when I receive start blocks. Try and roll them up into just one script. Not only will it run faster but should iron out some of those glitches.

As a teacher have you looked at ScratchEd? I've seen pacman/maze type games in there which may be of use to you.

I was looking your topic and finally i success myself.
I think you could have a look on my project: Creer un Minotaure https://scratch.mit.edu/projects/80185494/

Thanks
