Deal damage on collision
Hi, I want my game to work so if the enemy collides with the player the player loses 10 health but I don't know what to do and I've tried every tutorial out there. Please help I am desperate.
using UnityEngine;
using System.Collections;
public class PlayerVitals : MonoBehaviour {
public GameObject guiObject;
public int curHealth = 100;
public int maxHealth = 100;
public int recoveryAmount = 1;
public float recoverySpeed = 3;
public Color bloodColor = new Color(1.0f, 0.0f, 0.0f, 1.0f);
public Texture2D bloodyScreen;
public float fallDamageHeight = 8;
public AudioClip fallDamage;
[HideInInspector] public float percent;
private float alpha;
private float iv2;
private float minimumHealth = 40;
private float bmhRatio;
private PlayerMovement pm;
private CharacterController controller;
void Start() {
minimumHealth = 40;
pm = GetComponent<PlayerMovement>();
if(recoveryAmount != 0) {
StartCoroutine(Regenerate(0));
}
controller = GetComponent<CharacterController>();
}
void OnControllerColliderHit(ControllerColliderHit hit) {
Rigidbody rigid = hit.collider.attachedRigidbody;
if(rigid == null || rigid.isKinematic || hit.moveDirection.y < -0.3f) {
return;
}
Vector3 pushDir = new Vector3(hit.moveDirection.x, 0, hit.moveDirection.z);
rigid.velocity = pushDir * controller.velocity.magnitude * pm.pushPower / rigid.mass;
}
void OnGUI() {
GUI.color = new Color(bloodColor.r, bloodColor.g, bloodColor.b, alpha);
GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), bloodyScreen);
}
void FixedUpdate() {
alpha = Mathf.Lerp(alpha, 0.9f - (percent * 0.9f), Time.deltaTime * 7);
curHealth = Mathf.Clamp(curHealth, 0, maxHealth);
percent = (float)curHealth / (float)maxHealth;
iv2 = pm.impactVelocity;
if(curHealth <= 0) {
Die();
}
Repud.GetChild(guiObject, "health_text").GetComponent<TextMesh>().text = curHealth.ToString() + "/" + maxHealth.ToString();
Repud.GetChild(guiObject, "health_bar").SendMessage("UpdateSize", percent);
bmhRatio = maxHealth / minimumHealth;
if(pm.grounded && pm.floating && iv2 > 1) {
SendMessage("FallAnimation", iv2);
}
if(pm.grounded && pm.floating && iv2 > fallDamageHeight) {
FallDamage(((iv2 - (fallDamageHeight * 0.8f)) * ((iv2 - (fallDamageHeight * 0.8f)) * 0.5f)));
iv2 = 0;
pm.floating = false;
}
}
public IEnumerator Regenerate(int amount) {
curHealth += amount;
yield return new WaitForSeconds(recoverySpeed);
StartCoroutine(Regenerate(recoveryAmount));
}
private void FallDamage(float prc) {
if((int)(prc) <= 0) {return;}
ApplyDamage((int)prc);
audio.clip = fallDamage;
audio.volume = 0.02f;
audio.Play();
}
public void ApplyDamage(float amount) {
curHealth -= (int)amount;
}
public void Die() {
Destroy(gameObject);
}
}
This in JavaScript:
var health : int = 100;
function OnCollisionEnter (collision : Collision)
{
if (collision.tag == "Enemy")
{
health -= 10;
}
}
I know this is an old topic, but just in case anyone else is searching for a good answer to this, follow the answer by @create3dgames, and I would like to add right under the if statement
if(Health < 0 ) {
Health = 0;
}
This will prevent the health from going into negative numbers, which I doubt most people will want... Also, to be able to add enemy characters and have them be able to damage the player's health, I would change "var health : int = 100;" to "static public var health : int = 100;". This will allow you to call on the player's health in ANY other script in your project (I don't know if it works in csharp), as long as you call on it like "[name of the script here with var health in it, but remove the brackets].health", which is VERY useful when making a game.
Best of luck to anyone who struggles with this.
