[Solved]Help With Simple AI code

[LÖVEYoungGunnaTeam]

I need help to get the Hamster in the .love file to freely move from right to left and back. I have been trying for a few days now and thought the forums could help me out. I don't need anything fancy, but if its needed, please do explain. (All of us have a different coding style.) Thanks guys!! ~YoungGunna

I'm trying to decide if you're trying to get it to move back once it hits the side or if you're trying to get it to be randomized. I decided to do both. I have comments in the code as well as various other small changes.

Well, I am not sure about your intent, but from your previous code, it looks like you are trying to make the ball move left for 5 seconds, then right, and so on.
Try this. I am using a variable named "dir", which tells in which direction the ball should move. "-1" for left, "1" for right.
At start, direction is right (dir = 1).
In love.update, timer is updated using dt.
Each 5 seconds, direction is inverted (multiplying dir by -1) and timer is reset to 0, to be ready to count for 5 seconds again.
Position is updated adding each frame speed * dt * dir. Note that, when dir is positive, x will increase (as speed * dt * dir is positive), then the ball goes right. When dir is negative, x will decrease (provided that speed * dt * dir is negative), then the ball goes left.

PS:love.draw remains the same.

Code: Select all

function love.load()
	cpu = love.graphics.newImage("hamster.png")
	x, y, timer, speed, dir = 0, 300, 0, 100, 1
end

function love.update(dt)
	timer = timer + dt
  if timer >= 5 then 
    dir = dir * -1
    timer = 0
  end
  x = x + (speed * dt * dir)
end

EDIT: davidsdude was faster.

I may have been faster, but I believe you were more correct. I think that was their original intent, I just sort of forgot...
So how 'bout it's a draw.

Both of you helped out, and i wasn't very clear my intent. Thank you both! I like the option of the randomized movement, but the whole timed movement was what i was trying to go for (and failed.) This was for a game i'm going to make, but needed help. (One man coding isn't fun.) Anyway, thanks guys!!

No problem! Glad we could help!
