A small library of composable multi-touch controllers for Codea that implement various game control mechanisms

codea-controllers's Issues

ClampLen returns NaNs when applied to zero vectors

Fix by adding this condition to clampLen:

if(vec == vec2(0, 0)) then return vec end

Handle CANCEL events

Controllers should forget touches when they are cancelled to cope with the user switching away from and back to Codea.

Smoothed Path controller

A controller for line-drawing control, as used in Flight Control and countless other games.

The controller should have a "select" callback, like the Catapult control

Add "select" callback to Catapult controller

The "select" callback would be used for selecting an item in the game to control. The callback would return the start point of the catapult if something is selected or nil if there is nothing where the user has touched, in which case the catapult gesture would not be started.
