FirstPersonLauncher with Softbody itself - nbac85 - 18-12-2020
Hey i would like to shoot some softbodies.
so i want to do a mix between the actor spawner and the fps launcher.
the softbody does not have a rigidbody so how do apply initial velocity to the particles?
i did pose the whales with obi
and now i need to shoot crabs.

Same way as you'd do with a rigidbody:
Quote:softbody.AddForce(velocity,ForceMode.VelocityChange);
See:
https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html
https://docs.unity3d.com/ScriptReference/ForceMode.VelocityChange.html
Only difference between rigidbodies and softbodies is that rigidbodies have a single linear velocity (measured at its center of mass), while softbodies have multiple velocities (one per particle). But you can use AddForce() the same way with both.

yes thanks ! i have to add very high values else its working perfectly!
Code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Obi;
public class ActorSpawner : MonoBehaviour {
public ObiActor template;
public int basePhase = 2;
public int maxInstances = 32;
public float spawnDelay = 0.3f;
private int phase = 0;
private int instances = 0;
private float timeFromLastSpawn = 0;
public float power = 2;
// Update is called once per frame
void Update () {
timeFromLastSpawn += Time.deltaTime;
if (Input.GetKeyDown(KeyCode.Space) && instances < maxInstances && timeFromLastSpawn > spawnDelay)
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
GameObject go = Instantiate(template.gameObject,ray.origin, Quaternion.identity);
go.transform.SetParent(transform.parent);
ObiSoftbody sb = go.GetComponent<ObiSoftbody>();
sb.AddForce(ray.direction * power * 10000, ForceMode.Force);
go.GetComponent<ObiActor>().SetPhase(basePhase + phase);
phase++;
instances++;
timeFromLastSpawn = 0;
}
}

Remember that the change in velocity or acceleration = force/mass, so if the softbody mass is high, you will have to use a large force for it to result in enough acceleration. Using ForceMode.VelocityChange as indicated above might be a better idea if you don't want mass to affect launch speed.
