A good way to do this would be to collide if Vector3.Dot (or Vector2.Dot) of Player.velocity && rayInfo.normal (for a simple raycast) is less than 0. In order for this to work you need to go...

Almost positive I know your issue. I think you need to use cannon.transform.rotation (not local rotation) and cannon.InverseTransformDirection instead of Transform Direction for these two lines:...

Go to the tab "edit"-->"project settings"-->"physics" and look at the "min penetration for penalty" variable. If that variable is 0.05, then that is precisely the behavior the Unity3d dev team...

What you are looking for is the Dot product. You want to disable movement when the player is inside a wall, so if(Vector3.Dot(velocity,hit.normal) < -0.1) velocity = Vector3.zero; //when you get...

First something that might give you a little insight. Physics.SphereCast will return false if the imaginary sphere starts its "sweep" while already inside of an object. Basically, you can think of...

First off, that code is indeed in a script attached to the wall right? I would do it the other way around (attach the script to the cannon ball, which then finds a "wall" tag on collision), but it...

My best guess would be to add a co-routine that is called every 1-5 seconds that sorts through the nearest objects and either enables or disables the collider based on whether or not they are within a...

I think you might be able to get this to work with fixed arrays. Usually with the javascript arrays you use float, int, string, etc (not GameObject from what I know). var arr : GameObject[]; //make a...

Assuming this is a 2.5D sidescroller, what you want to do is raycast downwards and find the normal. First I would add an empty gameObject to the scene gameObject-->create empty. Rotate this object...

that's probably because the model is rotated. In order to get this to work well, i would recommend: function Awake () //called when the arrow is instantiated, this is different than Start() {...

I think you can add the following to OnCollisionEnter: var temp0 : Vector3; var temp1 : Vector3; var temp2 : Vector3; temp0 = collision.transform.position; temp1 = transform.position; //Step1 temp2 =...

The issue is that you are trying to redefine an already defined variable. Lets say unity has a variable transform.position, what you are essentially trying to say is private var transform.position =...
