What do you mean? Where to use dt?

the dt in update( dt ) only says the update loop " hey man, you need dt in your loop !! ".
use dt with values you increase / decrease in your love.update. i.e for the player movement:

Code: Select all



player.x, player.y = 0, 0
player.xvel = 200

end

function love.update( dt )

if love.keyboard.isDown( "right" ) then
player.x = player.x + player.xvel * dt	-- xvel is the speed on the x axis
end

end


This let your game run with the same speed on every computer.

Have you read the wiki, or did you just skip ahead thinking you knew programming already? (Seems like you must have used some other language in the past, unless you copied and pasted all that code.) Well, love2d is different. I'm trying not to be to mean, but we really shouldn't have to be telling you this, it's fundamental. You should read a tutorial, literally any tutorial, before going forward. Try this: https://love2d.org/wiki/Tutorial:Gridlocked_Player
I LÖVE, therefore I am.

Slow that ball down!!!

Seriously in the time it took to bring the game into focus (<1 second) the CPU had scored 45 points
Your screen is very zoomed in...

Yep, that's the dt thing.
On the bright side, the game as it stands is a nice way to brag about your computer's speed.

"Dude, on MY computer, the computer got 100 points in one second!"
"Yo, shut up, bra, hawha!"
I LÖVE, therefore I am.
