Node Or Pathfinding ? which is better?

Hi guys,

I am trying for a tower defense game and i want to know, node or pathfinding for path find in game? My point is cpu usage and memory.

any idea?

Is the path fixed and unchanging (can you block the path with towers)? Then you don't need pathfinding.

If your path can change dynamically in game, then you need pathfinding.

Ok, thanks oosyrag , and about cpu and memory usage?

A fixed path should use significantly less resources than pathfinding, especially if you have large amounts of objects pathfinding.

thank you man,
