我正在开发一款 3D 游戏,目前我正在走路,但是当我走一步时,我会遇到运行时错误
'表达式:向量迭代器不兼容'
这里是第一次调用walking的地方:
void Packets::handleMoving(Player* p, Stream* s)
{
printf("handling movement for player: %s\n", p->getUsername());
int newWalkCmdSteps = (p->packetSize - 5) / 2;
if(newWalkCmdSteps > WALKING_QUEUE_SIZE)
{
printWarning("Warning: walkTo(%d) command contains too many steps (%d).\n", p->packetType, newWalkCmdSteps);
return;
}
PlayerHandler::resetWalkingQueue(p);
Pos temp;
vector<Pos> tempPathWaypoints;
int firstStepX = s->readSignedWordBigEndianA();
for(int i = 0; i < newWalkCmdSteps; i++) {
temp.x = s->readSignedByte();
temp.y = s->readSignedByte();
tempPathWaypoints.push_back(temp);
}
int firstStepY = s->readSignedWordBigEndian(); //absPos
int isRunning = s->readSignedByteC() == 1; //seems always be 0 so useless..
PlayerHandler::addToWalkingQueue(p, firstStepX, firstStepY);
for(int i = 0; i < newWalkCmdSteps; i++) {
tempPathWaypoints[i].x += firstStepX;
tempPathWaypoints[i].y += firstStepY;
PlayerHandler::addToWalkingQueue(p, tempPathWaypoints[i].x, tempPathWaypoints[i].y);
}
}
我通过使用断点还发现底部 forloop 似乎是问题所在。
当我在以下添加断点时
tempPathWaypoints[i].x += firstStepX;
我收到运行时错误,但在此之前的任何地方都没有。
这是我其余的步行功能。(对于这个线程来说,把它放在 pastebin 太长了)
我很确定错误是基于 addToWalkingQueue 但我不确定
