This is the first step of a little app done in Unity. The goal is to escape the covid, each time the Player is touch by the virus, it multiplies\u2026<\/p>\n

\"D:\\LAURENT\\Downloads\\WhatsApp<\/p>\n

The labyrinth is created in Sketchup, but could have been created in any 3D software and exported as a 3DS file in Unity.<\/p>\n

<\/p>\n

The site is prepared as Navigation Static<\/p>\n

<\/p>\n

In the navigation panel it is defined as Walkable<\/p>\n

<\/p>\n

And then it is possible to bake the mesh.<\/p>\n

<\/p>\n

As a result, a walkable zone is defined<\/p>\n

<\/p>\n

We will use Third Person Controller – Basic Locomotion FREE<\/p>\n

<\/p>\n

Check that the Tag Player is set.<\/p>\n

<\/p>\n

Create a virus model<\/p>\n

<\/p>\n

Add a Nav Mesh Agent Component<\/p>\n

<\/p>\n

Add a CSharp script<\/strong><\/p>\n

using System.Collections;\nusing System.Collections.Generic;\nusing UnityEngine;\nusing UnityEngine.AI;\n\npublic class Seek : MonoBehaviour\n\n{\n\npublic float Mass = 15;\npublic float MaxVelocity = 3;\npublic float MaxForce = 15;\n\nprivate Vector3 velocity;\n\npublic Transform target;\n\nprivate void Start()\n\n{\nvelocity = Vector3.zero;\n}\nprivate void Update()\n{\nvar desiredVelocity = target.transform.position - transform.position;\ndesiredVelocity = desiredVelocity.normalized * MaxVelocity;\nvar steering = desiredVelocity - velocity;\nsteering = Vector3.ClampMagnitude(steering, MaxForce);\nsteering \/= Mass;\nvelocity = Vector3.ClampMagnitude(velocity + steering, MaxVelocity);\ntransform.position += velocity * Time.deltaTime;\ntransform.forward = velocity.normalized;\nDebug.DrawRay(transform.position, velocity.normalized * 2, Color.green);\nDebug.DrawRay(transform.position, desiredVelocity.normalized * 2, Color.magenta);\n}\n}\n<\/pre>\n
Add the script to the Virus<\/p>\n
<\/p>\n
As target, the Head Top End can be chosen\u2026<\/p>\n
Test the application<\/p>\n
<\/p>\n
Now the virus has to multiply;<\/p>\n
Add a sphere to the virus<\/p>\n
<\/p>\n
<\/p>\n
Uncheck the Mesh Renderer<\/p>\n
<\/p>\n
Enlarge the Sphere Collider and ckeck the is Trigger box<\/p>\n
<\/p>\n
Add an Audio Source for an audio feedback, add an audio file<\/p>\n
<\/p>\n
Add the Contamination script<\/p>\n
<\/p>\n
using System.Collections;\nusing System.Collections.Generic;\nusing UnityEngine;\n\npublic class Duplicate : MonoBehaviour\n\n{\n\nAudioSource _audioSource;\n\npublic AudioClip _audioClip;\npublic Transform Spawnpoint;\npublic GameObject Virus;\npublic Duplicate(GameObject virus)\n\n{\n\nVirus = virus;\n\n}\nvoid Start()\n{\n\n_audioSource = GetComponent<AudioSource>();\n\n}\nvoid OnTriggerEnter(Collider other)\n{\n\nif (other.CompareTag(\"Player\"))\n\n{\nInstantiate(Virus, Spawnpoint.position, Spawnpoint.rotation);\n_audioSource.PlayOneShot(_audioClip);\n}\n\n}\n\n}\n<\/pre>\n
Once done create a Prefab from the Virus.<\/p>\n
<\/p>\n
The Prefab holds all scripts and heriarchies.<\/p>\n
<\/p>\n
Put Prefabs in the scene and play!!<\/p>\n
