Hello everyone, I need help in disabling collision in the game on Unity IL2CPP, I need the car to drive through walls, how do you turn on the collision function and the car can drive through walls, what method or what is responsible for disabling collision, tell me who knows, I will be very grateful!!!

Idk if you know hooking, but I can give ideas on what to hook & modify.

what method or what is responsible for disabling collision

You can disable gameobjects' colliders by hooking:

 bool UnityEngine.Collider.get_enabled()

But hooking and changing this directly would mean that all colliders would get disabled. Meaning that not only would you go through walls, but also through the ground.

My idea:

1. Hook a Start() function or something similar that runs once. And also make an Array variable like: monoArray<void**>* GameObjectArray

2. Filter gameobjects: with either by tag

static GameObject[] UnityEngine.GameObject.FindGameObjectsWithTag(string tag)

(if walls etc. have a specific tag, you need to check game files)

or get all gameobjects for now, e.g.

static Object[] UnityEngine.Object.FindObjectsOfType(Type type)

type for the parameter:

static Type System.Type.GetType(string typeName)

So it would be FindObjectsOfType(GetType(CreateMonoString ("GameObject")).
In the start hook assign the array variable:

GameObjectArray = FindGameObjectsWithTag(CreateMonoString("wall" (etc.))

3. Hook an update function

4. Once you have the array of gameobjects, (I think) you can access the collider component with:

Component UnityEngine.GameObject.GetComponent(Type type)

So you could make a loop in the update hook like:

for (int i = 0; i < GameObjectArray->length; i++)
    {
        void* GO = GameObjectArray->getPointer()[i];
void* component = GetComponent(GO, GetType(CreateMonoString("Collider")
    }

and change the enabled state with a trigger and the setter:

for (int i = 0; i < GameObjectArray->length; i++)
{ 
    void* GO = GameObjectArray->getPointer()[i];

    void* ColliderComp = GetComponent(GO, GetType(CreateMonoString("Collider");

    //void UnityEngine.Collider.set_enabled(bool value)
    set_Enabled(ColliderComp, !colliderOff);
 }

if you use the FindObjectsOfType, you still need to filter the gameobjects. E.g. with int UnityEngine.GameObject.get_layer() or comparing UnityEngine.Object.get_name():

for (int i = 0; i < GameObjectArray->length; i++)
{ 

   void* GO = GameObjectArray->getPointer()[i];
if (get_layer(GO) == x //or name logic)
{
   void* ColliderComp = GetComponent(GO, GetType(CreateMonoString("Collider");

   //void UnityEngine.Collider.set_enabled(bool value)

set_Enabled(ColliderComp, !colliderOff);
}
 }

Hope you can get something out this mess

You can also manually, and more precisely, disable or remove the colliders of walls by modifying the game files. But that takes a lot of time

Thank you!!!

But the problem is not solved yet

What do you have so far? I tested my method on one game and it worked. Although, I couldn't figure out how to handle the gameobject array, because the game crashed once a new scene with new objects was loaded.
