How do I execute a function a a particular x and y? Do I put it in the argument, bracket thing at the end of the function? I searched but couldn't find anything.

What exactly do you want? What do you mean by 'at a particular x and y'?

If I have a function that draws something, how do I make it at a cirtain x, & y without actually putting it in.


Like love.graphics.draw( drawable, x, y, r, sx, sy, ox, oy )

insead of entering x, and y, can one enter nothing for the x, & y but still make it execute at a particular place?

Like

function drawthing()
love.graphics.draw(drawable)
end

How can I make drawthing occur at a particular x, & y without actually entering it in? Is there another way?

I feel so stupid. -_-

How would it possibly know where to draw the thing unless you tell it? However, you don't necessarily have to enter numbers literally. You could draw it to coordinates from a variable. For example, if you wanted to draw something at the cursor, you would do:

Code: Select all

function love.draw()
    love.graphics.draw(ourimage, love.mouse.getX(), love.mouse.getY())
end

Maybe you mean that you want to use default values for x and y?

Code: Select all

function drawthing(drawable, x, y)
  x = x or 100
  y = y or 200
  love.graphics.draw(x,y, drawable)
end

This function will accept x and y as parameters. If you don't pass them, it will assign them 100 and 200.

Code: Select all

  drawthing(drawable, 500, 600) -- draws drawable thing on x=500, y=600
  drawthing(drawable) -- draws drawable thing on x=100, y=200

[Robin]

Code: Select all

function drawthing(drawable, x, y)
  x = x or 100
  y = y or 200
  love.graphics.draw(x,y, drawable)
end

Fail: it should be love.graphics.draw(drawable, x, y).

@Xoria: do you expect LÖVE to know where you want your image to be drawn, or something else?
