Help. Need to fix the jumping

Post by ShadowPenguins »

i need help to make the jumping better and need help with the collisions heres my code.

Code: Select all

local bump = require "bump"
world = bump.newWorld()

player = {
	x = 0,
	y = 0,
	width = 32,
	height = 64,
	jump = 300,
	gravity = 500,
	runSpeed = 400,
	xVelocity = 0,
	yVelocity = 0,
	terminalVelocity = 800
}

function player.setPosition(x, y)
	player.x, player.y = x, y
end

function player.update(dt)
	player.move(dt)
	player.applyGravity(dt)
	player.collied(dt)
end

function player.move(dt)
if love.keyboard.isDown("d") then
	player.xVelocity = player.runSpeed
elseif love.keyboard.isDown("a") then
	player.xVelocity = -player.runSpeed
else
	player.xVelocity = 0
	end
	if love.keyboard.isDown("space") then
			player.y = player.jump 
	end
end

function player.applyGravity(dt)
	if player.yVelocity < player.terminalVelocity then
		player.yVelocity = player.yVelocity + player.gravity * dt
	else
		player.yVelocity = player.terminalVelocity
	end
end

function player.collied(dt)
	local futureX = player.x + player.xVelocity * dt
	local futureY = player.y + player.yVelocity * dt
	local nextX, nextY, cols, len = world:move(player, futureX, futureY )
	
	for i = 1, len do
	local col = cols[i]
	if col.normal.y == -1 or col.normal.y == 1 then
		player.yVelocity = 0 
		end
	end
	
	player.x = nextX
	player.y = nextY
end

function player.draw()
	love.graphics.setColor(0,255,0)
	love.graphics.rectangle("fill", player.x, player.y, player.width, player.height)
end

local block = {
	x = 120,
	y = 500,
	width = 300,
	height = 32
}

local block2 = {
	x = 50,
	y = 400,
	width = 100,
	height = 32
}

function love.load()
	player.setPosition(love.graphics.getWidth()/2, 0)
	player.img = love.graphics.newImage('purple.png')
	world:add(player, player.x, player.y, player.width, player.height)
	world:add(block, block.x, block.y, block.width, block.height)
	world:add(block2, block2.x, block2.y, block2.width, block2.height)
end

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

function love.draw()
	love.graphics.draw(player.img, player.x, player.y, 0, 1, 1, 0, 32)
	love.graphics.setColor(0, 255, 0)
	love.graphics.rectangle("line", block.x, block.y, block.width, block.height)
	love.graphics.setColor(0, 0, 255)
	love.graphics.rectangle("line", block2.x, block2.y, block2.width, block2.height)
end
