I see a couple problems: - ToList returns an object of Type List and you're attempting to assign it to a Transform[]. - ToList(Transform) should read ToList(transform) (get the instance name, not the...

You'll need a couple things. 1. An efficient way to detect proximity. [Physics.OverlapSphere][1] or just colliders set as triggers are good for this. This is so you can say, "Enemy is close to player,...

It is very easy to copy any object. Use [UnityEngine.Object.Instantiate][1] You can also procedurally move things around very easily in unity: "GameObject.transform.position = someVector3;" You can...

What sort of DLL are you talking about here? A .net DLL can just be dragged in to unity (assuming it doesn't have any weird requirements like System.Windows). If it's a native dll (from C++ or...

I'm not sure why the script wouldn't compile straight out of the box, but the compile error looks simple enough to fix. It's an interface you implement rather than a base class to extend. You can use...

It would look something like this. You could put this script on a GameObject and in the editor set up as many units in that array as you want. I do recommend using better names than I did: public class...

Sounds like z-fighting. Try using a shader that includes an offset. Simple example: Shader "No More Z Fighting/Foreground Element" { Properties { _MainTex ("Main Texure (RGBA)", 2D) = "" {} } SubShader...

There's a couple different things going on in From Dust, but I think the basic thing you're looking for is the [Marching Polyhedrons][1] algorithm. It's used to generate a 'shell mesh' over a point...

You can use the GUIStyle.CalcHeight function for this: http://docs.unity3d.com/Documentation/ScriptReference/GUIStyle.CalcHeight.html I'm assuming that the variable 'Answer' is your GUIStyle and...

If you keep track of your "wall" or plane as point-normal, it's really easy ([Khan academy link for the math involved][1]). The code would look something like this: Vector3 wallToObject = wall.position...

You should be able to make them all the same mesh without adding tris. In your 3D modeling tool just combine all the meshes in to a single object. For prop-sized objects, that's pretty much the rule of...

Bug in your code. You probably want this: void Start () { GameObject newobj = new GameObject("Testing"); newobj.transform.parent = transform; // this transform, not the parent...

The problem you have is here: movement.x = Input.GetAxis("Horizontal") * speed; movement.z = Input.GetAxis("Vertical") * speed; You're applying movement in "world-space". If you want to move in...
