Collision Detection

[reuben2011]

I know there has been a lot of people saying "We want collision detection! Blah! Blah!" I'm not going to be that type of person that just demands a feature. Instead, I was wondering, if the people creating Alice 3.0 could access all of the "points" of any particular object.

For example, if we assign a letter for every three-dimensional position, if object1 contains points in the positions {a, b, c, d} and object2 contains points in the positions {d, e, f, g} then it would show as a collision since they share a common point {d} in the same position. I know that most objects contain more than four points, so I'm not sure if checking for collisions using this method would be practical.

So yeah, Alice could have a built in "isColliding" function, using two parameters for the two different objects and the result would return true if the any points in the first object are in the same position as the second object.

So yeah... to sum it up in hard code:

isColliding = function(object1, object2)
{
//object.points is an array containing all the points in that object.
//intersection is a function that returns the commonalities between two arrays
newArray = intersection(object1.points, object2.points);
if (newArray.size >= 1)
{
return true;
}
}

I don't know what data the Alice development team has access to, but hopefully this might help.
