1, y
1), radius r 1, the coordinate position of card j is denoted as (x
2, y
2), radius r
2, satisfy following mathematic(al) representation and then bump:
(cards_positions[i][0]-cards_positions[j][0])2+(cards_positions[i][1]-cards_positions[j][1])2<(r1+r2)2；
After the collision, move according to the move function of card button and the movement angle control card button of the rear card button of collision, wherein, after the collision, the move function of card button does not change, and the direction of motion of card button can change.The direction of motion of card button is the symmetry direction of former direction two card button circle center line connecting directions during about collision after the collision, namely the movement angle of the card button after the collision is that the former direction of card button is about the symmetric angle of two card button circle center line connecting directions, in the practical application, when if this symmetric angle is negative angle, then this negative angle is added 2 π, and get the mould of 2 π.
For example, the coordinate position of card button i is denoted as (x1, y1), direction of motion cards_angles[i], the coordinate position of card button j is denoted as (x2, y2), direction of motion cards_angles[j], when bumping, two card button circle center line connecting directions
α=arctan ((cards_positions[i] [1]-cards_positions[j] [1])/(cards_positions[i] [0]-cards_positions[j] [0])), the obtain manner of direction of motion that then collides latter two card button is as follows:
a1=2a+π-cards_angles[i]
cards_angles[i]=（a1+2π）mod2π
a2=2a+π-cards_angles[j]
cards_angles[j]=（a2+2π）mod2π。
