FUNCTION: 0E93F98
They're the same Basically I’m trying to create a modular control scheme. Because due to the nature of our game we want more then 1 way to control the player.
Currently we have a player.lua which returns a “player” display object with all the physics and what not applied.
We have a control.lua which has two functions. One enables and disable movement for a specific target, in this case it’s the player. And another which interprets the touch information and adds an impulse the “player”.
In the level.lua we create an instance of control.lua function that determines the direction and adds impulse, and then we toggle touch detection on.
The problem is that “e” for some reason never reaches the instanced function and I have no idea why. Alternatively, is it possible to change the properties of something in one module from another without instancing the function? (E.G. Change “Player”'s [Which is located in level1.lua) velocity by adding impulse to it from (controls.lua)? [import]uid: 123782 topic_id: 22410 reply_id: 322410[/import]
