[英]How would I go about implementing java code in c# and vice versa?
I'm attempting to create a game in unity, but Java isn't able to be used in it, so any premade scripts are in C#. 我试图统一创建游戏,但是无法在其中使用Java,因此任何预制脚本都在C#中。 I want to add some stuff in the mechanics of the game, which requires me to alter variables and values in the script, but I only know how to do so in java, so how would I make it so they can effectively communicate? 我想在游戏机制中添加一些内容,这需要我更改脚本中的变量和值,但是我只知道如何在Java中进行更改,因此我将如何使其能够有效地进行交流?
An example from c#: 来自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;
}
}
and my java code: 和我的Java代码:
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);
}
}
}
I'm trying to make it so when shift is pressed, the velocity is changed to a larger value than usual for a small time, but i have no idea where to even begin 我试图做到这一点,所以当按下shift键时,速度会在短时间内更改为比平常大的值,但是我什至不知道从哪里开始
Unity only supports scripts written in C#. Unity仅支持用C#编写的脚本。 It used to also support a version of JavaScript they called UnityScript, but they moved to only officially support C# now. 它曾经还支持一个称为UnityScript的JavaScript版本,但是现在它们仅迁移到正式支持C#。 Fortunately C# is really similar to Java, so you shouldn't have too much trouble translating your scripts to C#. 幸运的是,C#与Java非常相似,因此将脚本转换为C#不会有太多麻烦。 The main challenge would be learning the Unity library. 主要的挑战是学习Unity库。
I wrote some code below that updates an object's speed using Unity library functions. 我在下面编写了一些代码,这些代码使用Unity库函数来更新对象的速度。 Unity has a lot of built-in ways of helping you out as a developer so I'd recommend the tutorials on Unity's website for more on getting started with it. Unity有很多内置的方法可以帮助您成为开发人员,因此我建议您在Unity网站上推荐教程,以获取更多有关使用它的入门信息。
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);
}
