// TO-DO:
// -- When Ronaldo Scores, Messi moves to the centre circle but when Messi Scores, Ronaldo doesn't
// -- Still need to remove the goalkeeper code



// Done: 
// -- Ronaldo doesn't Return to original position when a goal is scored:
// -- Ronaldo obj and mtl looks really good
// -- Score only has one count for all the goals scored: e.g. 5 : 0, messi scored 3, ronaldo scored 2
//      -- It has something to do with the goals



// Issues:
// -- Ronaldo logicalAgent2 "thinks" the ball is one space up
// -- Goals still count if it's beyond the "goalposts"
