Troubles with A*

[seven]

Hello. I'm using Cowlol's A* Pathfinding Script (click) but have had some troubles with it. Here is the code I used:

char = 46

x = 13

y = 25

goal_node = Node.new(x, y)

path = A_Star_Pathfinder.new

(goal_node)

char = 46

x = 13

y = 16

goal_node = Node.new(x, y)

path = A_Star_Pathfinder.new

(goal_node)

char = 46

x = 20

y = 14

goal_node = Node.new(x, y)

path = A_Star_Pathfinder.new

(goal_node)

char = 46

x = 13

y = 25

goal_node = Node.new(x, y)

path = A_Star_Pathfinder.new

(goal_node)

char = 46

x = 28

y = 25

goal_node = Node.new(x, y)

path = A_Star_Pathfinder.new

(goal_node)

char = 46

x = 28

y = 29

goal_node = Node.new(x, y)

path = A_Star_Pathfinder.new

(goal_node)

char = 46

x = 1

y = 25

goal_node = Node.new(x, y)

path = A_Star_Pathfinder.new

(goal_node)

Each code tag represents a script call, all in one parallel process event. In game, though, the specified event doesn't move. I know this isn't a problem with the map- I tried it using the Move Route event command and it worked- so what am I doing wrong with A*?

You call script just looks off. That's all:

node = Node.new(x, y)

char = $game_map.events[event_id]

path = A_Star_Pathfinder.new(node, char, false)

path.generate_path

I get that error when I try it that way. Here's the code I used:

node = Node.new(13, 25)

char = $game_map_events[46]

path = A_Star_Pathfinder.new(node, 

char, false)

path.generate_path

You copied it wrong, it's $game_map.events[46], not $game_map_events[46]. Though it's not necessary to pass an event (it can figure it out if you give it a number).

This is a more compact version of SephirothSpawn's code that you can try (hopefully you won't confuse . with _ this time :wink

node = Node.new(13, 25)

char = 46

path = A_Star_Pathfinder.new(node, char)

 

I'd like to note that pathfinding takes a lot of processing (i.e. slows down your game) and it's generally not a wise idea in a parallel process. One of the examples in the pathfinding demo does this to simulate a caterpillar system but that was mainly to show certain features of the script, rather than the right way to do it.
