Help with Sprite Interaction and Collision Detection in a Maze Game
I am working on a maze game project, and I'm having trouble implementing sprite interaction and collision detection. How can I make my character sprite detect and respond when it collides with walls in the maze? Additionally, I would like to create a win condition when the character reaches the end of the maze. Any suggestions or sample code to get me started on the right track would be greatly appreciated@

Help with Sprite Interaction and Collision Detection in a Maze Game
Let's assume your player moves instead of your maze. As a sample maze below, the red circle is the player, the black walls are the maze, and the green line is the win condition.

Yeah, I know, it's an immaculate maze design that definitely no one would be able to figure out how to reach the end. But you can expand it with your own time. Let's see how we would implement this.
First, we want to make sure the player can move, but not through walls. The walls should be the maze sprite. You can move the win condition sprite around to match where your maze ends.

when green flag clicked
go to x: () y: () // set x and y to where your maze starts
forever
if <key [w v] pressed?> then
change y by (5)
if <touching [maze v] ?> then
change y by (-5)
end
end
if <key [s v] pressed?> then
change y by (-5)
if <touching [maze v] ?> then
change y by (5)
end
end
if <key [a v] pressed?> then
change x by (-5)
if <touching [maze v] ?> then
change x by (5)
end
end
if <key [d v] pressed?> then
change x by (5)
if <touching [maze v] ?> then
change x by (-5)
end
end
if <touching [win v] ?> then
stop [all v]
end
end
