Passing Variables in functions/state

dthrasher90 · April 14, 2017

How can I pass a variable from a function to a state? I am trying to log the new position of a ball on a field. So i have a closure that moves the ball around. The outer function moves the players and the inner function tweens the football to the players, based on a switch statement. Inside the switch, the function is correctly logging the new location. How can I pass that new location variable to my main game state? It looks like this, basically, Im trying to pass that ball.y to make it easily accessable. Ive tried to make it a global, but that didnt seem to work. I may add, these functions are in another js file, than my index.html. Any thoughts?

function play1 (){

//move players

function move ball to players()

{

switch :

//switch stuff here

case 1:

//move ball to player

console.log(ball.y)

}

Make sure that your another js file is loaded before you start the which state. Then uses a function to return your values.

My code is super huge, is there another way to do this? Basically i am lining everyone up to the center and the center to the football, tracking the distance of the football to move the line of scrimmage (more functions to come for this). the idea is to use the case to simulate a qb choosing which reciever to throw the ball to. The code is fine and dandy and it works well, with little lag, maybe there is a better way? I want to get football.y so I can start keeping global stats.
