Creating Platforms

Now let's add platforms for our player to jump on. We'll create a table of platforms and draw them all.

Platform Data Structure

We'll store platforms as a list of rectangles:

lua
platforms = {
    {x = 0, y = 250, width = 400, height = 50},   -- Ground
    {x = 50, y = 180, width = 80, height = 15},   -- Platform 1
    {x = 200, y = 130, width = 100, height = 15}, -- Platform 2
}

Drawing Multiple Platforms

We use a for loop to draw all platforms:

lua
for i, platform in ipairs(platforms) do
    love.graphics.rectangle("fill", platform.x, platform.y, platform.width, platform.height)
end

Complete Code with Platforms

lua
function love.load()
    player = {
        x = 50,
        y = 200,
        width = 30,
        height = 40,
        speed = 200,
        velocityY = 0,
        gravity = 800,
        jumpForce = -350,
        onGround = false
    }

    -- Define platforms
    platforms = {
        {x = 0, y = 250, width = 400, height = 50},    -- Ground
        {x = 50, y = 190, width = 80, height = 15},    -- Low left
        {x = 180, y = 150, width = 100, height = 15},  -- Middle
        {x = 300, y = 100, width = 80, height = 15},   -- High right
    }
end

function love.update(dt)
    -- Horizontal movement
    if love.keyboard.isDown("left") or love.keyboard.isDown("a") then
        player.x = player.x - player.speed * dt
    end
    if love.keyboard.isDown("right") or love.keyboard.isDown("d") then
        player.x = player.x + player.speed * dt
    end

    -- Apply gravity
    player.velocityY = player.velocityY + player.gravity * dt
    player.y = player.y + player.velocityY * dt

    -- Reset ground state
    player.onGround = false

    -- Check collision with all platforms
    for i, platform in ipairs(platforms) do
        if checkCollision(player, platform) then
            -- Land on top of platform
            if player.velocityY > 0 then
                player.y = platform.y - player.height
                player.velocityY = 0
                player.onGround = true
            end
        end
    end

    -- Screen boundaries
    if player.x < 0 then player.x = 0 end
    if player.x + player.width > 400 then
        player.x = 400 - player.width
    end
end

function checkCollision(a, b)
    return a.x < b.x + b.width and
           a.x + a.width > b.x and
           a.y < b.y + b.height and
           a.y + a.height > b.y
end

function love.keypressed(key)
    if (key == "space" or key == "w" or key == "up") and player.onGround then
        player.velocityY = player.jumpForce
        player.onGround = false
    end
end

function love.draw()
    -- Sky
    love.graphics.setColor(0.4, 0.7, 1)
    love.graphics.rectangle("fill", 0, 0, 400, 300)

    -- Draw platforms
    love.graphics.setColor(0.4, 0.8, 0.4)
    for i, platform in ipairs(platforms) do
        love.graphics.rectangle("fill", platform.x, platform.y, platform.width, platform.height)
    end

    -- Player
    love.graphics.setColor(1, 0.3, 0.3)
    love.graphics.rectangle("fill", player.x, player.y, player.width, player.height)

    -- Eyes
    love.graphics.setColor(1, 1, 1)
    love.graphics.circle("fill", player.x + 10, player.y + 12, 5)
    love.graphics.circle("fill", player.x + 22, player.y + 12, 5)

    love.graphics.setColor(0, 0, 0)
    love.graphics.circle("fill", player.x + 12, player.y + 12, 2)
    love.graphics.circle("fill", player.x + 24, player.y + 12, 2)

    love.graphics.setColor(1, 1, 1)
    love.graphics.print("Jump on the platforms!", 10, 10)
end

Try it! Jump up and land on the different platforms!
