示例1: applyAvoidance

inline

{
	// only avoid the player if not in the background
	if (this->layer < LR_ELEMENTS10)
	{
		if ((dsq->game->avatar->position - this->position).isLength2DIn(128))
		{
			avoid(accumulator, dsq->game->avatar->position);
		}
	}


	//return;

	if (avoidTime>0) return;

	VectorSet closestObs;
	VectorSet obsPos;
	//Vector closestObs;
	int range = 10;
	int radius = range*TILE_SIZE;
	Vector p;
	TileVector t0(position);
	TileVector t;
	for (int x = -range; x <= range; x++)
	{
		for (int y = -range; y <= range; y++)
		{
			TileVector t = t0;
			t.x+=x;
			t.y+=y;
			if (dsq->game->isObstructed(t))
			{
				p = t.worldVector();

				closestObs.push_back(this->position - p);
