C++ Agent::incSugar方法代码示例

/*
 * Check location for agent. If present check to see if due to die.  If so then remove all sugar.
 * If agent is not dying then check each parent to see if they are dying.
 * If they are take the correct share of their sugar (total sugar divided by number of children.
 * Note: We do not bother to check if any of their other children may be dying - just to simplify code
