概要
UdonSharpで自分が書いたコード集です。走り書きです。
Merlin-san/UdonSharp
UdonSharpを用いることで、ノード無し、C#コードでUdonを書けます。詳しくは以下。

オブジェクトのアクティブをオンオフ(ローカル)
using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
<summary>
</summary>
public class ToggleBtnLocal : UdonSharpBehaviour
{
[SerializeField] private GameObject target;
public override void Interact()
{
target.SetActive(!target.activeSelf);
}
}
オブジェクトを一つづつアクティブ/非アクティブ化(ローカル)
using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
<summary>
</summary>
public class SwitchObjsLocal : UdonSharpBehaviour
{
[SerializeField] private GameObject[] objs;
private int activationIndex = 0;
private void SetActiveObjs()
{
for (int i = 0; i < objs.Length; i++)
{
objs[i].SetActive(i == activationIndex);
}
}
private void Start()
{
SetActiveObjs();
}
public override void Interact()
{
activationIndex++;
if (activationIndex >= objs.Length)
{
activationIndex = 0;
}
SetActiveObjs();
}
}
UIスライダーの値をUIテキストに反映(ローカル)
using UdonSharp;
using UnityEngine;
using UnityEngine.UI;
using VRC.SDKBase;
using VRC.Udon;
public class SliderValToText : UdonSharpBehaviour
{
[SerializeField] private Slider slider;
[SerializeField] private Text targetText;
public override void Interact()
{
targetText.text = slider.value.ToString();
}
}
オブジェクトの位置をマテリアルのパラメータに反映
using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
<summary>
</summary>
public class LocalPosToMaterialParam : UdonSharpBehaviour
{
[SerializeField] private MeshRenderer meshRenderer;
[SerializeField] private string paramName = "_Color";
[SerializeField] private float scale = 4.0f;
private void Update()
{
Vector3 p = transform.localPosition * scale;
meshRenderer.material.SetColor(paramName, new Color(
Mathf.Clamp(p.x, 0.0f, 1.0f),
Mathf.Clamp(p.y, 0.0f, 1.0f),
Mathf.Clamp(p.z, 0.0f, 1.0f)
));
}
}
Playerの動きのパラメーターを設定
using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
<summary>
</summary>
public class PlayerMovingParameterSetter : UdonSharpBehaviour
{
[SerializeField] private float runSpeed = 2.0f;
[SerializeField] private float walkSpeed = 4.0f;
[SerializeField] private float strafeSpeed = 2.0f;
[SerializeField] private float jumpImpulse = 3.0f;
[SerializeField] private float gravityStrength = 1.0f;
private void Start()
{
VRCPlayerApi localPlayer = Networking.LocalPlayer;
if(localPlayer == null)
{
return;
}
localPlayer.SetWalkSpeed(runSpeed);
localPlayer.SetRunSpeed(walkSpeed);
localPlayer.SetStrafeSpeed(strafeSpeed);
localPlayer.SetJumpImpulse(jumpImpulse);
localPlayer.SetGravityStrength(gravityStrength);
}
}
TeleportTo 特定の位置にプレイヤー座標を設定
using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
<summary>
</summary>
public class TeleportToTest : UdonSharpBehaviour

[SerializeField] private Transform target;
public override void Interact()
{
var player = Networking.LocalPlayer;
player.TeleportTo(target.position, target.rotation);
}
}

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;

{
[SerializeField] private Vector3 vel = Vector3.up * 10.0f;
public override void Interact()
{
var player = Networking.LocalPlayer;
player.SetVelocity(vel);
}
}
同SetVelocity ピックアップした状態で押すとピックアップオブジェクトの前方に速度を設定
※オブジェクトにVRCPickupをアタッチ、VRC Pickupのパラメーターを設定する必要あり
using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
public class VelocitySetterForward : UdonSharpBehaviour
{
[SerializeField] private float speed = 10.0f;
private Transform _transform;

{
_transform = GetComponent<Transform>();
}
public override void OnPickupUseDown()
{
var player = Networking.LocalPlayer;
player.SetVelocity(speed * _transform.forward);
}
}

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
public class ImmobilizeTest : UdonSharpBehaviour
{
private bool isImmobilize = false;
public override void Interact()
{
var player = Networking.LocalPlayer;
isImmobilize = !isImmobilize;
player.Immobilize(isImmobilize);
}
}

ビルドなしで、Unity上でVRChatクライアントをエミュレートできます。
再生ボタンを押すとほぼ即実行されます。
効率が上がるので非常におすすめです。
