[英]How would I go about implementing java code in c# and vice versa?
我試圖統一創建游戲,但是無法在其中使用Java,因此任何預制腳本都在C#中。 我想在游戲機制中添加一些內容,這需要我更改腳本中的變量和值,但是我只知道如何在Java中進行更改,因此我將如何使其能夠有效地進行交流?
來自c#的示例:
protected override void ComputeVelocity()
{
Vector2 move = Vector2.zero;
move.x = Input.GetAxis ("Horizontal");
if (Input.GetButtonDown ("Jump") && grounded) {
velocity.y = jumpTakeOffSpeed;
} else if (Input.GetButtonUp ("Jump"))
{
if (velocity.y > 0)
velocity.y = velocity.y * .5f;
}
targetVelocity = move * maxSpeed;
}
}
和我的Java代碼:
public void keyPressed(KeyEvent e)
{
if(e.getKeyCode() == KeyEvent.VK_SHIFT)
{
endTime = (System.currentTimeMillis() / 1000);
timePassed = endTime - startTime;
if(timePassed >= 2)
{
//try to set a time limit or something
velocity = overMaxVelocity;
//set velocity to above usual max for dodgeTime
startTime = dodgeTime + (System.currentTimeMillis() / 1000);
}
}
}
我試圖做到這一點,所以當按下shift鍵時,速度會在短時間內更改為比平常大的值,但是我什至不知道從哪里開始
Unity僅支持用C#編寫的腳本。 它曾經還支持一個稱為UnityScript的JavaScript版本,但是現在它們僅遷移到正式支持C#。 幸運的是,C#與Java非常相似,因此將腳本轉換為C#不會有太多麻煩。 主要的挑戰是學習Unity庫。
我在下面編寫了一些代碼,這些代碼使用Unity庫函數來更新對象的速度。 Unity有很多內置的方法可以幫助您成為開發人員,因此我建議您在Unity網站上推薦教程,以獲取更多有關使用它的入門信息。
public float speed = 2;
public float speedUpFactor = 2;
// Get the Rigidbody component attached to this gameobject
// The rigidbody component is necessary for any object to use physics)
// This gameobject and any colliding gameobjects will also need collider components
Rigidbody rb;
// Start() gets called the first frame that this object is active (before Update)
public void Start(){
// save a reference to the rigidbody on this object
rb = GetComponent<Rigidbody>();
}
}// Update() gets called every frame, so you can check for input here.
public void Update() {
// Input.GetAxis("...") uses input defined in the "Edit/Project Settings/Input" window in the Unity editor.
// This will allow you to use the xbox 360 controllers by default, "wasd", and the arrow keys.
// Input.GetAxis("...") returns a float between -1 and 1
Vector3 moveForce = new Vector3(Input.GetAxis ("Horizontal"), 0, Input.GetAxis("Vertical"));
moveForce *= speed;
// Input.GetKey() returns true while the specified key is held down
// Input.GetKeyDown() returns true during the frame the key is pressed down
// Input.GetKeyUp() returns true during the frame the key is released
if(Input.GetKey(KeyCode.Shift))
{
moveForce *= speedUpFactor;
}
// apply the moveForce to the object
rb.AddForce(moveForce);
}
