1	Game Development / Newbie & Debugging Questions / Re: LIbgdx: Tips on best practices for tilemap (Polygon?) collision detection	on: 2014-07-25 21:20:56
Quote from: Norakomi on 2014-07-25 20:13:57 Cool! This seems like a good way to do it. And how would you set up the collision detection? I'm not using box2D and not using bodies atm in my gameworld. The way I am usually doing collision detection is keep track of player's x & u coordinates; & use that to set up a rectangle that will be used for collision detection. I assume I should create a body and give it the dimensions of that same rectangle and then check if a body intersects with another body ?? Seems like you don't know to much about box2d. Do some research on it. It may look a little confusing at first but its quite simple to use specially if you are just needing collision detection.

You can use box2d and create bodies with the polygon data from the object layer.

It is pretty simple, I managed to do it with this:

public void loadBodies(MapLayer objects, Array<Body> bodies) {
      BodyDef def = new BodyDef();
      PolygonShape shape = new PolygonShape();

      for (MapObject object : objects.getObjects()) {
         if (object instanceof RectangleMapObject) {
            Rectangle rect = ((RectangleMapObject) object).getRectangle();

            def.position.x = (rect.x + rect.width / 2) / 10;
            def.position.y = (rect.y + rect.height / 2) / 10;
            def.type = BodyType.StaticBody;

            shape.setAsBox(rect.width / 2 / 10, rect.height / 2 / 10);

            bodies.add(world.createBody(def));
            bodies.get(bodies.size - 1).createFixture(shape, 0);
         }

         if (object instanceof PolylineMapObject) {
            float vertices[] = ((PolylineMapObject) object).getPolyline()
                  .getTransformedVertices();
            for (int x = 0; x < vertices.length; x++) {
               vertices[x] /= 10;
            }
            ChainShape shape2 = new ChainShape();
            shape2.createChain(vertices);
            def.position.set(0, 0);
            cuerpos.add(world.createBody(def));
            cuerpos.get(cuerpos.size - 1).createFixture(shape2, 0);
         }
      }
   }

This code works for rectangle objects and polyline objects. The divitions by 10 are there because for me 1 meter is equivalent to 10 pixels, but you can use any ratio you like.

Hope it helps you.

LibGDX uses abstraction on its methods so layouts and jframes/panes wouldn't work on a mobile device I think.

Ok, here's the deal. I'll get a tablet in a few weeks. Will install a psx emu. Will play Silent Hill. And then (if I manage to get some time) will try my best to do a remake/demake.

WOW i didn't know there was a LD about remakes

Hi JGO. It's been a while since the last time I wrote some code (life....) and I was thinking: "It would be cool if I had time to make a little 2D game. Probably a horror one. I GOT IT!!!! I'll make a 2D remake of Silent Hill 1" Has there ever been 2d remakes of 3d games? If so, do they have the "charm" of the original? Wouldn't you like to play a top-down Resident Evil 4? What are your thoughts about the topic?

Game Development / Newbie & Debugging Questions / Re: Problem fetching a Chip-8 opcode

on: 2014-06-24 01:18:56

@burntpizza thank you that solve my problem.

Now i have another question: Why in every Chip-8 tutorial appears as

1	memory[pc] << 8 \| memory[pc+1]

Is there something different in how java manages bits?

14	Game Development / Newbie & Debugging Questions / Re: Problem fetching a Chip-8 opcode	on: 2014-06-24 00:57:42
@liquidnitrogen Thank you, that actually worked but for some reason the first opcode came wrong and the next in line came perfect. Sadly if the first opcode is wrong the whole thing wont work.

Game Development / Newbie & Debugging Questions / [SOLVED] Problem fetching a Chip-8 opcode

on: 2014-06-24 00:46:41

I'm really not sure if this is the right forum to ask this question, as this is not a game but an emu/interpreter but I'm freaking out over here.

Long story short:

I have to fetch the first two bytes from a byte array, which are A2 and CC (in hexadecimal of course).

For that task I do the following...

1	int opcode = memory[pc] << 8 \| memory[pc+1]

But instead of give me "A2CC" together it gives me "FFCC"

Please JGO I'm about to hang myself.

Thank you.

I really dont get why you would want to create several cameras for such a simple effect like parallax. Even if its not too heavy performance-wise, you would just over complicate your code.

Thanks but that's not the answer I'm looking for. I already know how to use Raycast Callback. What I need is to know how to get the fixture that is closer to the origin of the ray.

19	Game Development / Newbie & Debugging Questions / LibGDX Box2D Raycast problem	on: 2014-05-16 05:30:20
Hi, JGO. I have a problem with Raycastcast Callback: When I return the fraction it does give me the closest hit point but not the closest fixture. I need the closest fixture because I'm using rays as enemy "eyesight". Hope you can help me. Thanks in advance.

Quote Self-made, it's based on a variation of my pathfinding system's search pattern, just instead of finding a path, it assigns a light level at all the places it checks. The distance it checks is based on how "bright" the light is. Wink Do you really only have 1 year of experience as your profile says? You do very cool stuff.

Game Development / Newbie & Debugging Questions / [FIXED] Rotating animations problem in LibGDX

on: 2014-04-25 01:01:35

Hello, JGO.

I'm trying to make a top down shooter with libgdx. As you already know, in a top down (Bird's eye) game, you don't need to make every side of a sprite because you just have to rotate the sprite and there is where my problem lies.

When you ARE NOT using animations you can just set the texture of the sprite

1	sprite.setTexture(texture)

and then call the method

1	sprite.setRotation(angleInRadians)

BUT I AM using animations so how can I get the texture when I'm calling

1	animation.getKeyFrame(...)

.

Calling animation.getKeyFrame(...).getTexture() does not work as it returns the whole texture pack

Correct me if I'm wrong, but it seems like when your character moves diagonally, what you are doing is make him move at the same speed in the X and Y values. To explain myself: If character moves to the right, you set his Xvelocity value to (let's say) 50, and if he moves up you set his Yvelocity to 50, but if he moves diagonally to right-up you set his X and Y velocity to 50 which doesn't make him move at 50 but at the square root of 50^2+50^2 which is 70.71, and that increase of speed makes his movement look kinda funny (at least in my opinion).

Rayvolution, you seem to be very good at pixel art. May I know what program do you use to paint? And, if possible, any tutorial link?

Start learning LibGDX for a couple of days and then you will realize that with a couple of "if" statements you can make the input work in any platform.
