me.getX() obtain onball Of x coordinate , If ＜0, namely onball In our half ( Our goal coordinate is -15), Just put x The assignment is me.getX()+10( Try to kick forward ), And use opp1.getY() Get the other goalkeeper y coordinate , If it is regular, it will y The assignment is -0.6, Otherwise, it is assigned as +0.6, That is, try to kick towards the other half of the goalkeeper's goal .

abs_x and abs_y It is based on the midpoint of the opponent's goal , take x The axis is reversed , Under the established coordinate system onball coordinate . The next few if else It is determined according to this coordinate kick The type of . use t Pass it as a parameter to each kick function ,t That is, the coordinates of the position you want to kick ,t Medium x and y If there is no assignment, use the default parameter 15 and 0.

2.findCloestOppDistance Function gets the opposite distance onball The distance of the nearest player .

3.findOppDistance Function gets the opposite distance onball The latest player .

NUM_AGENTS by 11.

hinder if The sentence uses a way similar to the challenge arena to find the nearest .

k That is, the number of opposing players . Call this function later , according to k To judge whether there are many players on the other side , If you don't have much, take the ball , Pass more .
