[Windfield physics] Jumping and collision detection problem

[ilovelove2019]

Hello. It's me again. I'm making a platformer and I get this problem. Let's get straight to the point. Here is some of my code:
Main.lua:

Code: Select all

function love.load()
    Object = require"classic"
    require "player"
    anim8 = require "anim8"
    windfield = require("windfield-master/windfield")
    world = windfield.newWorld()
    world:setGravity(0, 100)
    
    ground = world:newRectangleCollider(0, 550, 800, 50)
    ground:setType('static')
    world:addCollisionClass('Ground')
    world:addCollisionClass('Player')
    ground:setCollisionClass('Ground')
    
    player = Player()
end

function love.update(dt)
    world:update(dt)
    player:update(dt)
end

function love.draw()
    player:draw()
    world:draw()
end

player.lua:

Code: Select all

Player = Object:extend()

function Player:new()
    self.width = 50
    self.height = 37
    self.x = 200
    self.y = 200
    self.sx = 1
    self.onGround = false
    
    ....
    
    --physics
    self.collider = world:newRectangleCollider(200, 200, 27, 30)
    self.collider:setCollisionClass('Player')
end

function Player:update(dt)
    
    if love.keyboard.isDown("left") then
        self.collider:setX(self.collider:getX()-1)
        self.sx = -1
        self.anim = self.animations.run
    end
    if love.keyboard.isDown("right") then
        self.collider:setX(self.collider:getX()+1)
        self.sx = 1
        self.anim = self.animations.run
    end
    if love.keyboard.isDown("up") and self.onGround==true then
        self.collider:applyLinearImpulse(0, -100)
        self.anim = self.animations.jump
        print("ok")
        
    end
    if love.keyboard.isDown("down") then
       
    end
    
    if self.collider:enter('Ground') then
        onGround = true
        print("yes")
    end
    function Player:draw()
    self.x = self.collider:getX()---37 / 2-6
    self.y = self.collider:getY()--- 50 / 2+ 6
    self.anim:draw(self.sprites, self.x, self.y, nil, self.sx, 1, self.width / 2, self.height / 2)
end

    
    
    ----

    
end

I press 'up' but it not jump, not have 'ok' print to the screen. Can you help me? If you have better method for the player movement, please teach me. Thank you so much! Hope you will help me soon

Bonus: I think my collision is wrong. I don't know what is the right method for detect collision in windfield. Pro please help me. Thank a lot!

Ok. I give up and change to bump. Thanks everyone.

I also made a box2d wrapper if you want to try : https://github.com/4v0v/physics.
