rigidbody.AddForce doesn´t work in c#
Hi,
I´m trying to make a FPSCharacter swimm in water at a specific height level. I´m using rigidbody.AddForce to add a force that pushes the rigidbody up. However, AddForce isn´t working. I saw annother Question and it seems like i have to unchek "is kinematik" for it to work. But if i do that, i can run through the terrain and i get a few other Bugs too. If you know how to use AddForce with a kinematik rigid body, please let me know. And also, if you know another way to let a rigidbody swim on water, please let me know to.
You should use ForceMode.Impulse for instant forces like jumping and ForceMode.Force for constant forces that are applied every FixedUpdate()
eg.
rigidbody.AddForce(10.0f, ForceMode.Impulse);
That woesn´t the problem. I can swimm now, but one problem was that if I´m walking under water and change the direction with the mouse, like I do over the water, I´m walking in the same direction as before. I have to stop and start walking again to change the direction, any idea why that is happening?
I'm not too sure about that. $$anonymous$$aybe you can show me your script so i get a better picture of what's happening
Ok here is the Script. It isn´t the best, but i think it should work.
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class Swimmer : $$anonymous$$onoBehaviour { public Vector3 $$anonymous$$Position; public Vector3 maxPosition; public GameObject controllingObject; public GameObject mainLight; public Color defaulColor; public Color underwaterColor; public float underWaterGravity; // Use this for initialization void Start () {
}
// Update is called once per frame
void Update () {
float x = controllingObject.gameObject.transform.position.x;
float y = controllingObject.gameObject.transform.position.y;
float z = controllingObject.gameObject.transform.position.z;
if (x <= maxPosition.x && y <= maxPosition.y && z <= maxPosition.z && x >= $$anonymous$$Position.x && y >= $$anonymous$$Position.y && z >= $$anonymous$$Position.z) {
controllingObject.GetComponent<Rigidbody> ().AddForce (new Vector3 (0f,10f,0f), Force$$anonymous$$ode.Impulse);
print ("under");
//controllingObject.GetComponent<Rigidbody>().
Light mlight = mainLight.GetComponent<Light>();
mlight.color = underwaterColor;
} else {
//Physics.gravity = new Vector3 (0f, -9.81f, 0f);
//controllingObject.GetComponent<Rigidbody> ().AddForce (new Vector3 (0f,0f,0f), Force$$anonymous$$ode.Acceleration);
controllingObject.GetComponent<Rigidbody> ().velocity = new Vector3 (0f,0f,0f);
controllingObject.GetComponent<Rigidbody> ().angularVelocity = Vector3.zero;
Light mlight = mainLight.GetComponent<Light>();
mlight.color = defaulColor;
}
}
}
