Coding marathon

I have been coding for a week, like 3-4 hours every day, and also writing the game script, RPG system, and a few pages in my last novel. I have been trying code in the test project (the one I abandoned) and then doing thi things "right" in the prototype. Im pleased to say that I found how to properly implement drag and drop. The sample was there in my PC, waiting for me to look at it, and it was totally different to the approach I was taking.

I was trying to avoid using IDragHandler and the other interfaces, because I thought it was harder, yet, I was wrong. Actually, it is easier. Of course, I needed some basic code I took from the sample, but from there I have learned to implement not only drag and drop, but also mouse button events, mouse enter/exit, etc. All this while keeping control of what GameObject generated the event, via BaseEventData and derived classes.

Im working to implement drag and drop in the inventory for The Key of the World, which will take a few days, because it demands to fix the item system and make sure that a few details work as expected. The code will be available in github as soon as it is ready.

Unity3d isometric camera tutorial

I had pending this since a month ago, so Im forcing myself to post it today. The goal is to provide a fully functional isometric like system that you can use with few or none modifications in your own game. So, lets get started.

Start Unity3d and in your scene, add an empty GameObject, we will call it target. Create a camera object and drag it to target to make it child. The result looks like this:


Now select Camera and set the values to this:


For a true isometric like feeling, ortho projection is essential. You could use perspective, but it is not the same. Play with Size to suit your needs (we will be using this later, when implementing zoom).

Now, lets create an script named CameraController, or whatever, and drag it to target GameObject. Lets implement scrolling, the easier part: go to Update() and add the following code:

if (Input.GetKeyDown(KeyCode.W)) {
            dir = UP;
        } else if (Input.GetKeyDown(KeyCode.S)) {
            dir = DOWN;
        } else if (Input.GetKeyD…

TPS with free look tutorial, version 2 (and bugs)

After working a bit to improve the third person camera system I mentioned a couple of days ago, I found a few problems that I could fix, and other I cant. Here is the updated code:

public class PlayerControl : MonoBehaviour {

    public GameObject pivot;
    Animator anim;
    int direction = 0;
    int FORWARD  = 1;
    int BACKWARD = 2;
    int LEFT = 3;
    int RIGHT = 4;

    // Use this for initialization
    void Start () {
        //cam = gameObject.GetComponent<Camera> ();
        //Cursor.visible = false;
        //Cursor.lockState = CursorLockMode.Locked;
        anim = gameObject.GetComponent<Animator> ();
    }

    // Update is called once per frame
    void Update () {
        Vector3 rot;

        if (Input.GetKeyDown (KeyCode.W)) {
            direction = FORWARD;
        } else if (Input.GetKeyDown (KeyCode.S)) {
            //go back
            direction = BACKWARD;
        } else if (Input.GetKeyDown (KeyCode.A)) {
            direction = LEFT;
        } …

Tutorial: building a modular character

Building character models with body parts have been an obsession for me in the last weeks. I have googled, asked, googled, and asked again, played with Unity3d editor, tested code, and so on. You can see the result of my work in the previous post. First of all, I have to say that what I achieved is mostly derived from this thread and the sample posted there. My code is a copy&paste of that sample. Also, you can find a more extense solution in this Gamedev.net forum thread.

First, lets start with the model, which obviously, is divided in the required sections. Lets say we have head, torso and legs. Each part must be exported to a separate fbx file, but it must include the skeleton. Then, export the skeleton without geometry to another fbx.

Im going to assume that you want to instantiate all components, and even player, at runtime, from a  C# script (no Unity editor involved, except for creating prefab an position marker), so, we will place the sections, the skeleton and everything…
