As i do not want to implement my own collision detection algorithm, i have found a HardonCollider library to do the heavy lifting for me.

I have followed the example code of the library but got an error even with a basic setup.

Code: Select all

    local hc  = require "hardoncollider"

    local hero
    local collider

    function on_collision(dt, shape_a, shape_b, mtv_x, mtv_y)

    end

    function love.load(arg)
        collider = hc(100, on_collision)
        hero = collider:addRectangle(30,30,16,16)
    end

Running this code will throw the following error message:

Code: Select all

PS C:\dev\love-0.10.0-win64> Error: main.lua:12: attempt to call method 'addRectangle' (a nil value)
stack traceback:
        main.lua:12: in function 'load'
        [string "boot.lua"]:437: in function <[string "boot.lua"]:433>
        [C]: in function 'xpcall'

I have been investigating the problem, but did not find any solutions nor anybody else who faced this error.

well. You use some outdated docs & samples...
There is no such method as addRectangle
HC has a new API... so, use some new sample from the url http://hc.readthedocs.org/en/latest/

Found it here search.php?keywords=HardonCollider
