How to path around blocked tiles with jumper?

[Brah]

I'm using jumper for pathfinding and was wondering how to get the algorithm to take into account tiles blocked by enemies and other objects when finding a path.

I figured out this problem by myself but I have another another question. How do I write a walkable tile function for jumper?

Are you referring to Yonaba's Jumper? https://github.com/Yonaba/Jumper
Stating which library you are using would be helpful.

You need to create and provide a callback function that will return simple 0 (wall)/1 (path) based on walkability, e.g.:

Code: Select all

function isWalkable(sector)
  if sector=='path' then
        return true
    else
        return false
    end
end

then follow example as shown on Github:

Code: Select all

grid_object = Grid(your_grid, true)
finder = Pathfinder(grid_object, 'JPS', isWalkable)
path = finder:setMode('ORTHOGONAL'):getPath(start_y, start_x, end_y, end_x)

thanks!

I think I have an older version of jumper because I don't have THETASTAR and my getPath coordinates are X,Y...
Do you have any stuff on weighted grids and movement costs?

Dijkstra?

Check this:

and maybe update your code to this version.

I tried using that version of Jumper and it causes my games to crash.

Dijkstra?

Whatever works I just need some psuedo code or an example

Not sure if it was really Dijkstra, maybe something like that.
