寻的导弹，他们如何工作？ [英] Homing Missiles, How Do They Work?

问题描述

我想创建什么

• 将发射导弹对球员，如果有选手发生碰撞的对象，玩家死亡。

问题

• 如何向玩家导弹的举动。

• How does the missile move towards the player.

如何使导弹的举动，使其不会马上直接走向球员（缓慢前进的角度）。

How do I make the missile move so that it does not instantly move directly towards the player(to slowly move on an angle).

我有一个公式，鼠标成为玩家和导弹去对待它。

I have a formula for the mouse to be the "Player" and the missile to go towards it.

        mouse = Mouse.GetState();

        mousePosition = new Vector2(mouse.X, mouse.Y);

        A = (mouse.X - Position.X);
        B = (mouse.Y - Position.Y);
        C = (A * A) + (B * B);

        C = (float)Math.Sqrt(C);

        Angle1 = A / C;
        Angle2 = B / C;

（图纸是最好的！）

这仅得到距离导弹的球员，现在我需要找到角度什么的移动导弹，请问我需要做什么？

This only gets the distance from missile to player, now I need to find the angle or something to move the missile, what do I need to do?

推荐答案

您可以得到的距离从一个点到另一个点，并把它转换成一个方向行去。

You can get the distance from one point to another, and turn that into a direction to go to.

//Find the delta time
float delta = (float)gameTime.ElapsedGameTime.TotalSeconds * 60;
//Find the direction
Vector2 direction = mousePosition - misslePosition;
direction.Normalize();
//Move towards it
currentPos += direction * delta;

这需要由经过时间相乘所以会出现一样的，不管你是在运行的FPS。

It needs to be multiplied by the elapsed time so it appears the same no matter what FPS you are running at.

您可能需要调整速度，但它应该创建这样一个规律：

You may need to adjust for speed, but it should create a pattern like this:

如果您希望导弹慢慢地向着目标，你可以尝试 MathHelper.Lerp 慢慢改变角度。

If you would like the missle to slowly turn towards the target, you can experiment with MathHelper.Lerp to slowly change the angle.
