Question by castleforce · Mar 17, 2012 at 10:24 AM · javascriptraycastprojectilejavacolliding

Launching a Projectile to a Raycast

Hey guys, I did ask this question before but have since done some coding and done a few things need from my last question.

This time all I need is for a projectile to launch from one point to the point where the ray cast is colliding. Is this possible?

If possible I need someone to explain to me (in laymen terms as my code is noob level) or a script in java that has what I need.

Regards,

CastleForce (Trent)

Hello Trent,

Hmmmmm, if you want to spawn from the point you hit you could do this:

 var power = 10;
 var projectile : Rigidbody;

 var launch = Instantiate(projectile, hit.point, //rotation and stuff);
 //then apply force.
 projectile.rigidbody.AddForce(Vector3.up * power);

 //or as I prefer:
 projectile.transform.TransformDirection(Vector3.up * power);
 //wait is this right? I don't know...... I don't know the code to my preference exactly....


What is does is it spawns a object at the point the raycast hit and it adds force to the projectile or moves it.

And if you want a object to move to the raycasthit you could do this(never used this before):

 var projectile : Rigidbody;
 var spawn : Transform;

 projectile.transform.position = Vector3.MoveTowards(spawn.position, hit.point, /*maxDistanceDelta =*/ 0);


The maxDistanceDelta is the max distance from the target. so if it's 0 it moves directly to it(if I'm right), but if it's in the negative if moves away, If the code doesn't work please notify me. I have never used this code so I don't know if it will work. And for some clarifaction:

Instantiate page

MoveTowards page

Remember don't just use the scripts read them then adjust them and/or use them.

Good luck Trent,

Hybris
