Since the most popular love.physics wrapper (aka. Windfield) is no longer maintained i've made mine:
I'm currently writing the documentation and i'll also make some demos.

I don't use push but in the doc there are those functions that should do the trick Convert coordinates: push:toGame(x, y) --convert coordinates from screen to game (useful for mouse position) --push:toGame will return nil for the values that are outside the game - be sure to check that before using ...

It's not useless a all ! You can't directly set values to a body or a fixture (fixture.x = "hello").
I use it in my physics library if you wan't a real usecase :

What I use : class.lua local Class = {} function Class:new() end function Class:extend() local obj = {} obj.__call, obj.__index, obj.super = self.__call, obj, self return setmetatable(obj, self) end function Class:__index(v) return Class[v] end function Class:__call(...) local obj = setmetatable({},...

Try using the zip version.

pgimeno in the game he gave, the object orbiting stay at the same distance all the time (see webm), I don't think you can get this result without normalizing the angle ?

Trigonometry friend. function orbit(x,y, tx, ty, distance) local _x, _y = tx - x, ty - y local angle = math.atan2(_y, _x) return math.cos(angle)*distance + x, math.sin(angle)*distance + y end local a = {x = love.graphics.getWidth()/2, y = love.graphics.getHeight()/2} local mouse = {x = 0, y = 0} loc...

I tried but I don't understand how your code work, "txtt" become empty after ending the first conversation that's as far as I went.

You have globals everywhere and functions that call them without being passed as argument. Also your variable names are not easy to understand to say the least.

I don't understand how this would be usefull, just use a variable to stock the previous key and voila ?

do a function ?
