Display whole map at end of game

[RamblinLane]

Hi

I followed the Callacades tutorial on Love2d Basics (https://youtube.com/playlist?list=PLqPL ... _h_JGLgGg2)

I added some coins to collect and each disappear as collected.

At the end of the game I want to zoom out to show the whole map.

Map is created in Tiled with 2 Layers

gameMap is loaded with STI
Windfield for the world
Camera to track the player

love.draw displays portion of map with

Code: Select all

function love.draw()
    cam:attach()
        if gameOver then
            gameMap:resize(screen.w, screen.h)
            gameMap:drawLayer(gameMap.layers["Ground"])
            gameMap:drawLayer(gameMap.layers["Trees"])
        else
            gameMap:drawLayer(gameMap.layers["Ground"])
            gameMap:drawLayer(gameMap.layers["Trees"])
            --coin.animation:draw(coin.spriteSheet, coin.x, coin.y, nil, .7, nil, 16, 13)
            for i, coin in pairs(coins)
            do
                coin.animation:draw(coin.spriteSheet, coin.x, coin.y, nil, .7, nil, 16, 13)
            end
            player.anim:draw(player.spriteSheet, player.x, player.y, nil, 6, nil, 6, 9)
            world:draw()
        end
    cam:detach()
end

if gameOver I want to zoom out and show the whole map on the screen

TIA

Figured it out

Draw full screen outside the camera

still want to figure out how to centre the image

Code: Select all

function love.draw()
    if gameOver then
        love.graphics.scale( math.min(screen.h / screen.mapH, screen.w / screen.mapW ) )
        gameMap:drawLayer(gameMap.layers["Ground"])
        gameMap:drawLayer(gameMap.layers["Trees"])
    else
        cam:attach()
            gameMap:drawLayer(gameMap.layers["Ground"])
            gameMap:drawLayer(gameMap.layers["Trees"])

            for i, coin in pairs(coins)
            do
                coin.animation:draw(coin.spriteSheet, coin.x, coin.y, nil, .7, nil, 16, 13)
            end

            player.anim:draw(player.spriteSheet, player.x, player.y, nil, 6, nil, 6, 9)

            world:draw()
        cam:detach()
        love.graphics.print(tostring(player.x) .. ":" .. tostring(player.y))
    end
end

Assuming you're drawing the image at 0,0 you would do something like this:

local image_w, image_h = image:getDimensions()
camera.x = math.floor((image_w - camera.w) / 2)
camera.y = math.floor((image_h - camera.h) / 2)

Then set your camera to camera.x, camera.y. This is assuming the camera uses coords for its top-left corner rather than its center or whatever. Obviously rename the variables to whatever you need them to be. FYI, the math.floor calls ensure you're dealing with integer co-ordinates, which helps images & text stay crisp and non-blurry.

Thanks milon will give it a try
