Applying force when colliding with several objects
Hi, Im currently working on a game which involves moving through obstacles and not getting knocked of the platform.
However I have a problem with forces. For each obstacle i have put a variable called type which indicates which way the is pushed if they collide with that object. (0 for push to the right and 1 for push to the left.) Then I reference the script attached to the object to check the type and push the player accordingly. Now I know this isn't the most efficient/understandable way of doing but I just want to make this work before improving efficiency. I suck at coding.
------------------------------------------------Obstacle code--------------------------
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class obstacle : MonoBehaviour
{
//static varaibles
public int type = 0;
public static bool knock = false;
public static bool knock2 = false;
void OnTriggerEnter()
{
if (type == 0)
{
knock = true;
}
if (type == 1)
{
knock2 = true;
}
}
}
-------------------------------------------Player code--------------------------------------------------------------------
void OnTriggerEnter()
{
if (obstacle.knock2 == true)
{
rb.AddForce(-push * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
}
Debug.Log("trigger");
if (obstacle.knock== true)
{
rb.AddForce(push * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
}
Now for the problem, When I pass through the first object i move like i should, i get knocked to the right and all is good. However when then hitting the second object nothing happens. If i miss the first object and hit the second one first then i move to the left like i should but all other objects after that do nothing apart from the ones of the same type. e.g if i hit an object that moves me to the right all the left objects will have no effect on me but the other right objects will. I think this is because the forces cancel each other out.I have tried using all the force types ; force, acceleration, impluse and VelocityChange but none solve this problem. I have tried moving the player directly when hitting an object with: rb.transform.Translate(Vector3.left push Time.deltaTime); for when rb =rigidbody this kinda works but this is not smooth, clunky and with forces it just looks better. Can anybody help?
you shouldn't use Time.deltaTime outside of Update(). Have you tried a flat value?
@$$anonymous$$atthewj866 I got rid of the Time.deltaTime in the trigger yet I'm still seeing the same results. I get pushed to the side by the first object i go through then when i go through the rest nothing happens.
I got I now!!!!!!!!!!!!!!! I wasn't setting the static bool equal to false once i had applied the force so the player would experience the same force from the first trigger. I was also doing Time.deltaTime in the void method so that ruined it as well. Everythings working the way it should be now. Thanks!!!
