Making an enemey follow the player

[warmthunder51]

Hello, I recently got into lua and love2d, I'm trying to make a very basic pac-man clone. Current I have a ghost as a circle that chases you but I cannot seem to figure out the code for it.

Code: Select all

 --movement for ghost
 if distX > 0 then
   ghost.x = ghost.x + 1
 elseif distX < 0 then
   ghost.x = ghost.x - 1
 end 


 if distY > 0 then
   ghost.y = ghost.y + 1
 
 
 elseif distY  < 0 then
   ghost.x = ghost.x - 1
 end

This is my current implementation, it works only for positive x and negative y, but not for negative x and positive y, i cant seem to figure out why it wont go in the other direction. Any help is greatly appreciated, also sorry if this is a stupid question or I missed something obvious.

That's very naive approach.

I didn't check your full code, but I would recommend something like this instead - grid pathfinding:

Code: Select all

elseif distY  < 0 then
   ghost.x = ghost.x - 1

X or y?

your right, it was just that, because i had 2 statments changing the x and no y, it cancelled the movements for left and there was no upwards movement, thank you!!
