Hi,
Noob in programming here(:3), also first post, so bare with. I've attached my .love file (that's what I'm supposed to do right?) because I'm having problems with moving a player entity. I think I've managed to create an entity (with the help of a friend) in the form of a turtle (sorry, my graphics skills are rather bad) that I would like to be able to make move around the screen, and stop at the edges of my arena. Also, I've also attempted to update to love 0.9.0, and it says in the compiled file that the game was made for another version. How can I fix this?
Thanks for putting up will my noobiness and for all replies
.

It just works fine here.

How exactly do you want it to move ? Randomly ?
Or does it supposed to follow a specific path ? Actually, when I say "path", I mean you have an ordered set of locations the entity should visit one after another.

I was hoping to be able to control my turtle by pressing the "WASD" keys to make it move left, right, front and back, rather than in a set path or randomly.
Thanks.

There are many ways to achieve that. A simple one is to use
love.keyboard.isDown and increase/decrease the x/y pair coordinates controlling the entity position accordingly. See the
hamster ball tutorial for reference.

I might be being an idiot here, if so sorry, but when I press the W,A,S,D keys it gives me an error...(and yes, I have replaced the "left", "right" etc. with WASD).
Am I not selecting the entity for adjusting its x and y? If so, how do I do this?
Thanks again.

Welcome to the forums, my dear William!
For the solution to all your problems look in gamestate.lua under updateTurtles(dt)

Side note, instead of posting the whole file for such problem, you could have posted the relevant code.
Glad it worked out, though.

That's a bit of a catch-22 isn't it? When someone post code snippets we request the whole thing, when they post the whole thing we request snippets. Maybe posting both would be more useful though.
