Unnamed Street Racer - Devlog

[SamohtVII]

Hi all,

UPDATE: Name: World Racing: Online
Play Store: https://play.google.com/store/apps/details?id=com.UndividedGames.Racer2022
App Store: https://apps.apple.com/us/app/world-racing-online/id1529222598

Platforms: Mobile iOS, Android
Description: A free roam multiplayer driving sim. The idea is there are “games” scattered throughout the level that players can pick up.
Traffic: Urban Traffic System
World: Classic City, Countryside
Networking: PUN2
Cars: Fantastic Race Cars
Discord: TBA
Demo: TBA, recommendations on distributing a demo to the public?

Here’s an outline of the games you can pick up.

Bounty: A bounty is placed on a car at random and the others have to smash into it and pin it down for a few seconds to capture them. Picture the old Need for Speed games. If they can escape they for the whole time the bounty wins.

Point to Point Race: A simple checkpoint race. Drive through each checkpoint and be first to the end.

The Car That Couldn’t Slow Down: The minimum speed will begin at 1kph and tick up each second. Be the last person to stay above the ever increasing speed limit or explode into flames.

Many more to come…

Devlog #1
I am back into game dev and have picked up a project that has been on and off for a while. Just something to play with when I have free time.
I’ve made some nice progress and would love to start the feedback process and generate some interests.
Also, it’s a multiplayer game and would you believe it’s pretty hard to debug a mobile game as a solo developer.
Anyway, I’ll work on getting some beta versions up so people can have some fun and provide some criticisms.

I have used Urban Traffic System to simulate the traffic. I have recently got 2 loops of traffic working. Each path has several cars looping around a part of the road. They are connected through a PhotonView so everyone’s traffic is synced at the same spot. It isn’t incredibly smooth as a connected person but so far it’s the best I have.

I feel the games are working well together although I think some issues can arise when players connect/disconnect mid game. I have tried to account for all scenarios but I think it will be an ongoing battle.

Hi All,

Creating some socials that I will post here and you can keep up to date.
Here are some screens of the latest progress.

• Traffic Sync’d between all racers.
• Traffic fills the whole world now.
• Custom rooms can be made to play with friends easier

Great physics.
But i think the environment needs to be popped up.
Anyway, how did you make the damage system? Did you purchase it on asset store or something?

I can’t remember where I got it but it is free. Here is the script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DeformationMeshesPack : MonoBehaviour
{
    public MeshFilter[] meshFilters;
    public MeshCollider[] colliders;
    public float ImpactDamage = 3f;
    public float radiusDeformate = 0.7f;
    public float maxDeformation = 0.16f;
    public float minVelocity = 5f;
    private Vector3[][] originalVertices;
    private float nextTimeDeform = 0f;
    private Vector3 sumPosImpacts = Vector3.zero;
    private Vector3 sumVelocityImpacts = Vector3.zero;
    private int sumImpacts = 0;

    private Rigidbody rigidB;
    private CarController carC;

    void Start ()
    {
        rigidB = GetComponent<Rigidbody>();
        carC = GetComponent<CarController>();

        originalVertices = new Vector3[meshFilters.Length][];

        for(int i = 0; i < meshFilters.Length; i++)
        {
            originalVertices[i] = meshFilters[i].mesh.vertices;
            meshFilters[i].mesh.MarkDynamic();
        }
    }

    void FixedUpdate()
    {
        if (Time.time - nextTimeDeform >= 0.2f && sumImpacts > 0)
        {
            float invCount = 1f / sumImpacts;
            sumPosImpacts *= invCount; // same sumPosImpacts / sumImpacts
            sumVelocityImpacts *= invCount;
            Vector3 impactVelocity = Vector3.zero;

            if (sumVelocityImpacts.sqrMagnitude > 1.5f)
            {
                impactVelocity = transform.TransformDirection(sumVelocityImpacts) * 0.02f;
                float myImpact = impactVelocity.x + impactVelocity.y + impactVelocity.z;
                carC.health -= sumVelocityImpacts.sqrMagnitude / 50;
            }

            if (impactVelocity.sqrMagnitude > 0)
            {
                Vector3 contactPoint = transform.TransformPoint(sumPosImpacts);

                for (int i = 0; i < meshFilters.Length; i++)
                {
                    DeformationMesh(meshFilters[i].mesh, originalVertices[i], meshFilters[i].transform, contactPoint, impactVelocity, i);
                }
            }

            sumImpacts = 0;
            sumPosImpacts = Vector3.zero;
            sumVelocityImpacts = Vector3.zero;
            nextTimeDeform = Time.time + 0.2f * Random.Range(-0.4f, 0.4f);
        }
    }

    private void DeformationMesh(Mesh mesh, Vector3[] originalVerts, Transform localTransfrom, Vector3 contactPoint, Vector3 contactVelocity, int i)
    {
        Vector3[] vertices = mesh.vertices;
        bool isDeformate = false;

        for (int j = 0; j < vertices.Length; j++)
        {
            Vector3 localContactPoint = localTransfrom.InverseTransformPoint(contactPoint);
            Vector3 localContactForce = localTransfrom.InverseTransformDirection(contactVelocity);
            float distance = Vector3.Distance(localContactPoint, vertices[j]);

            if (distance <= radiusDeformate)
            {
                isDeformate = true;
                Vector3 damage = localContactForce * (radiusDeformate - distance) * ImpactDamage;
                vertices[j] += damage;
                Vector3 deformation = vertices[j] - originalVerts[j];
                vertices[j] = originalVerts[j] + deformation.normalized * maxDeformation;
                //vertices[j] = vertices[j] + deformation.normalized * maxDeformation;
            }
        }

        if (isDeformate)
        {
            mesh.vertices = vertices;
            mesh.RecalculateNormals();
            mesh.RecalculateBounds();
            if (colliders[i] != null)
            {
                colliders[i].sharedMesh = mesh;
            }
        }
    }

    private void OnCollisionEnter(Collision collision)
    {
        if (collision.relativeVelocity.magnitude > minVelocity)
        {
            int impactCount = 0;
            Vector3 impactPosition = Vector3.zero, impactVelocity = Vector3.zero;

            foreach (ContactPoint contacts in collision.contacts)
            {
                impactCount++;
                impactPosition += contacts.point;
                impactVelocity += collision.relativeVelocity;
            }

            if (impactCount > 0)
            {
                float invCount = 1f / impactCount;
                impactPosition *= invCount; //same impactPosition / impactCount
                impactVelocity *= invCount;
                sumPosImpacts += transform.InverseTransformPoint(impactPosition);
                sumVelocityImpacts += transform.InverseTransformDirection(impactVelocity);
                sumImpacts++;
            }

            //here you play crash sound
        }

    }
}

Here are some recent screens I took:

I finally bit the bullet and released my game. I wanted to get it out now because like many other people I have another idea that I’m dying to get started.
There was a lot of scope creep and instead of trying to add everything I wanted I decided to polish what was already there.
Enjoy
