RichtText? It's already (mostly) finished.

• It is written entirely in LUA, not C++. Although apparently binding LUA is relatively easy so that could change.
• I am not a very experienced coder. This will actually be my first public release of any kind. (<- that's red flag if you just missed it)
• It is currently not in a very presentable state but is getting very close.

• Be able to create collision bodies shaped like rectangles (non-rotatable), circles, segments, and points.
• Frame independent (step-wise).
• A collision grid for the broad phase.
• Customizable responses but with simple, predefined "push-out" ones available.
• Automatically tweens drawing locations between steps so transitions are always smooth.
• Includes a useful vector class (currently this is built over a very ugly adaptation of hump vectors with some extra functionality)

function love.load()

   colsys = CollisionSystem:new() -- create a new collision system
   colsys.step_size = 0.01 -- steps update every 1/100 of a second
   colsys.step_max = 3 -- maximum amount of steps in one update

   --create new bodies for the ground and player
   player = Body:new("player", Shape:new("Circle", 50, 0, 16), colsys)
   ground = Body:new("ground", Shape:new("Rect", 0, 0, 400, 50) colsys)
 
   -- make a new callback for player and ground. The function will put the player's location above the ground.
   colsys.callback["player"]["ground"] = function(player, ground) player.next.y = ground.current.y - player.next.height end
end

function love.update(dt)
-- advance the collision system.
colsys.advance(dt)
end

function love.draw()
-- drawX() and drawY() will tween the correct values so drawing is always smooth
love.graphics.draw(player_image, player.drawX(), player.drawY())
end
