@abrown18 Please format your code with three of these ~ at the begging and end like this

displayMode(FULLSCREEN)

function setup() lives=3 w=WIDTH/2 h=HEIGHT/2 instr=true boxTab={} for z=1,10 do table.insert(boxTab,vec3(math.random(WIDTH,WIDTH+100), math.random(50,HEIGHT-50), math.random(4,10)))
end end

function draw() background(255, 255, 255, 255) strokeWidth(5) lives = lives - 1 if instr then instructions() else sprite("SpaceCute:Background",w,h,WIDTH,HEIGHT) sprite("SpaceCute:Rocketship",spx,spy,200) showBoxes() checkHit() end end function touched(touch) instr=false spx = touch.x+10 spy = touch.y end

function showBoxes() for a,b in pairs(boxTab) do sprite("Space Art:Asteroid Small",b.x,b.y) b.x=b.x-b.z if b.x<0 then b.x=math.random(WIDTH,WIDTH+100) b.y=math.random(50,HEIGHT-50) b.z=math.random(4,10)
end end end

function checkHit() for a,b in pairs(boxTab) do v1=vec2(spx,spy) if v1:dist(vec2(b.x,b.y))<75 then sprite("Tyrian Remastered:Explosion Huge",b.x,b.y) table.remove(boxTab,a) end end end

function instructions() fill(224, 149, 129, 255) fontSize(25) text("This is a game made by Andrew Brown",w,650) text("You have to dodge the asteroids",w,600) fontSize(20) text("Tap the screen to start.",w,500) end

Please use three (~) before and after your code to format it, I edited your original post to include this. To make lives just create a variable to hold the number of lives. example: lives = 3 then just subtract or add when needed. then use an if statment to check if lives == 0

@Prynok I seem to be a few seconds behind you!

@abrown18 See the code I added.

Just wondering, how could you write a game with tables, but not know how to add lives? If this is based off another game, please give credit

@CodeaNoob To each their own, I guess.
