我想了解如何制作一个可以在地图上顺畅行走的 AI(在窗口大小之间)。就像,如果人工智能到达了那个定义的地点,那么它就会走到另一个地点。这是我尝试过的,
首先,我得到一个从 0.0f 到 608.0f 的随机浮点数,因为我的窗口大小是 640,640。
void AIntelligence::GenRandom()
{
MapX = static_cast <float> (rand()) / (static_cast <float> (RAND_MAX / 608.0f));
MapY = MapX;
}
然后,我将我的精灵的当前位置传递给这个函数
void AIntelligence::RandomMove(float PosX, float PosY)
{
this->PosX = PosX;
this->PosY = PosY;
if (PosX == MapX || PosY == MapY) //If the current is the same as the generated random, then
{ generate it again.
GenRandom();
}
else
{
if (PosX < MapX || PosY < MapY) //If not then I see if the position less than the
{ generated and translate it.
this->PosX += 8.0f;
this->PosY += 8.0f;
}
else if (PosX > MapX || PosY > MapY)
{
this->PosX -= 8.0f;
this->PosY -= 8.0f;
}
else
this->PosX += 0.0f;
this->PosY += 0.0f;
}
}
在我的消息循环中,这是我调用该方法的方式
while (GetMessage(&Msg, NULL, 0, 0))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
Inputs->GetInput(); //Not related
Moving->RandomMove(PosX,PosY);
D3DXVECTOR2 SpritePos = D3DXVECTOR2(Moving->getPosX(), Moving->getPosY());
PosX = Moving->getPosX();
PosY = Moving->getPosY();
Graphic->ClearBegin(); //Begin the direct3d scene
Sprite->Begin(D3DXSPRITE_ALPHABLEND);
float Radian = D3DXToRadian(Rotation);
D3DXMatrixTransformation2D(&Mat, NULL, 0.0f, &SpriteScaling, &SpriteCenter, Radian, &SpritePos); // This is where the transformation is set.
Sprite->SetTransform(&Mat);
Sprite->Draw(Texture, NULL, NULL, NULL, D3DCOLOR_XRGB(255, 255, 255));
Sprite->End();
Graphic->EndPresent();
}
精灵确实移动了,但只是向右下方移动。一旦它到达同一个特定的位置,它只会在那里停留并振动......如果我的解释不够清楚或没有提供足够的信息,请原谅。
