[pygame] Moving a sprite along a map.

[aspersieman <aspersieman@xxxxxxxxx>]

Hello All

I'm relatively new to python and pygame. I'm making a sort of tower  
defense game, involving llamas and stuff. I have managed to generate a  
map, that can have its layout (a bunch of lines on a .png) read from a  
text file, and that creates a 'path' where the 'creeps' are supposed to  
run along.

My problem is, how do I program a 'creep' to run along a specific path on  
my map? What I would ideally like is for the 'creeps' to 'know' where to  
go, in other words they would always run in one direction along a winding  
path and this path can be randomly generated.

Can anybody suggest an algorithm or point me to a relevant example where I  
can have this answered please?

Thanks for any help :)

Nicolaas
