LÖVE

Hi guys
I use windfield and I need two objects to pass through each other, so I made one object as sensor object using setSensor funcion but I found windfield doesn't detect sensor object collision!
I used collider:enter() in update function to detect collision but it doesn't work, I used preSolve call back method as well but still it doesn't detect any collision while one object is sensor!
How do you handle it using windfield? something simple like a character who should collect stars or food!

I believe this should be posted under Support. Also windfield is 6 years old and even archived on Github, which is a good sign to never use it.
You can try using breezefield instead: https://github.com/HDictus/breezefield

Thanks dusoft, I try breezefield and sorry for wrong topic, I thought support section is just about Love itself!

I was thinking the same way originally. Tried windfield, it didn't work, tried breezefield, it worked, but I liked HardonCollider more. That was old and has issues between different versions.

However, in the end I just went the hard way and used raw love.physics class:

Yes I agree, I was trying windfield as simple way in normal test project not commerical game, but I think it worth using love.physics itself on many serious projects.
btw, is there any like button in this forum? or something like that to say thank you to people who help us? It's not cool to replay a post just to say thank you

Hey there before enter methodyou have add addtional code in windfield
(collected from windfield wiki)
function love.load()
world = wf.newWorld(0, 512, true)
world:addCollisionClass('Platform')
world:addCollisionClass('Player')

ground = world:newRectangleCollider(100, 500, 600, 50)
ground:setType('static')
platform = world:newRectangleCollider(350, 400, 100, 20)
platform:setType('static')
platform:setCollisionClass('Platform')
player = world:newRectangleCollider(390, 450, 20, 40)
player:setCollisionClass('Player')
-- extra code
player:setPreSolve(function(collider_1, collider_2, contact)
if collider_1.collision_class == 'Player' and collider_2.collision_class == 'Platform' then
local px, py = collider_1:getPosition()
local pw, ph = 20, 40
local tx, ty = collider_2:getPosition()
local tw, th = 100, 20
if py + ph/2 > ty - th/2 then contact:setEnabled(false) end
end
end)
end

function love.keypressed(key)
if key == 'space' then
player:applyLinearImpulse(0, -1000)
end
end
