Love2d touch functions?

The title was too short to explain my problem fully, so here it is:
Right now, keyboard movement controls for my game are working perfectly ("a" to move left, "d" to move right, "space" to jump). However, I also want to test movement on my Android phone, and I'm not sure how Love2d touch functions work (as the wiki isn't very clear). For example, after I get a camera set up (currently in progress), my player should be centered in the middle of the screen. A touch and hold on the left side of the screen would make the player move to the right, and a touch and hold on the right should make the player move to the left, with doubletap to jump. As soon as touch is released, the player should stop moving. Any suggestions as to how I should set this up?

What parts of the wiki are unclear?

Essentially all of the love.touch section, for a beginner like me. I'm specifically not sure how to check if a touch is within a certain area of the screen (and make the player move if so), or how to use touch ids.

If you do not need handling simultaneous touches, you don't need to use touch; you can just use the mouse functions.
If you need to handle simultaneous touches, the only significant difference between the mouse functions and the touch functions is that each touch (each finger in contact with the screen) is assigned an id, which you're given.
You can track how many touches there are, and at which coordinates, by using the id as the key of a table.
Untested:
Code: Select all
local touches = {}
function love.touchpressed(id, x, y)
touches[id] = {x, y}
end
function love.touchmoved(id, x, y)
touches[id][1] = x
touches[id][2] = y
end
function love.touchreleased(id, x, y)
touches[id] = nil
end
local function howManyTouches()
return #touches
end
function isRectangleBeingTouched(rect)
for k, v in pairs(touches) do
if rect:containsPoint(v[1], v[2]) then
return true
end
end
return false
end

I am no Love2D expert, (in fact I just joined) but it might use the mouse and you just have to add an if clicked statement for a mobile version.
