Any idea why this happens to my GUITexts?

EDIT:

I found out that the material on the GUIText object had been set to something wierd. Fixed.

You forgot to assign the font on the text or the font is missing the characters.

I want to do something as simple as rendering a sprite completely white and then lerp it to normal.
How do I do this? Do I need to write my own shader? Can I use a pre-built one? Can I do something completely different? I can't use material.color it seems, white just means normal colour there.

I'm making a third person game, and I'm using click-to-move. For some stupid ass reason the character goes crazy most of the time, and I have no idea why.

If I increase the distance in Vector3.Distance the character won't go crazy as often, but the position where the character is moving is way off.

// Current selected player
	public GameObject curPlayer;
	CharacterController controller;

	public float speed = 5.0f;
	public Vector3 position;

	void Start ()
	{
		controller = curPlayer.GetComponent<CharacterController>();

		position = curPlayer.transform.position;
	}

	void Update()
	{
		if (GameManager.gameRunning) 
		{
			if (Input.GetMouseButtonUp(1))
			{
				controller = curPlayer.GetComponent<CharacterController>();

				locatePosition();
			}
			moveToPosition();
		}
	}

	void locatePosition()
	{
		RaycastHit hit;
		Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);

		if (Physics.Raycast(ray, out hit))
		{
			position = hit.point;
		}
	}

	void moveToPosition()
	{
		if (Vector3.Distance(curPlayer.transform.position, position) > 1)
		{
			Quaternion newRotation = Quaternion.LookRotation(position-curPlayer.transform.position, Vector3.forward);

			newRotation.x = 0f;
			newRotation.z = 0f;

			curPlayer.transform.rotation = Quaternion.Slerp (curPlayer.transform.rotation, newRotation, Time.deltaTime * 10);
			controller.SimpleMove(curPlayer.transform.forward * speed);
		}
	}

UPDATE:

My Character controller's radius is 0.5 and the height is 1 if it even matters.
This is the only thing stopping me from proceeding with my game.

been trying to get the hang of unity for the last 5 days

I am making a 2D game and I added arm rotation in it and it's working properly well but there is one problem and that is when I am rotating the player example below.

//Player spawns with rotation
Vector3(0,0,0);

//And when it turns it changes to
Vector3(0,180,0);

The problem is that the arm is a child of the player so when the player turn to 180 the arm also rotates, is there a way to freeze only the Y rotation of the child object?
Also the arm Z axis rotates based on the mouse position that's why I can't freeze the whole rotation completely.

[NoRegard]

You could set the arm to [B]not [/B]be a child of the player, but just find the player object by tag or whatever, and have the arm's position be set to the player's position.

Progress! There's a hud now and laps are now a thing. Also, look at that paintjob!

I did think about doing that but to be honest having the arm not attached to the player doesn't make much sense since it's part of him.

Nevermind I fixed the problem.
I was trying to modify the Y axis but I actually had to modify the X axis.

I'm doing a puzzle-based 2D sidescroller, I'm looking to start off with an optimal base and the last thing I want to do is have to go back and build it from the ground up when I hit performance issues later on.

[B]How should I be generating the world and calculating collisions?[/B]
I want to build the basic collision mesh of the world from squares/rectangles, for consistency when it comes to designing puzzles. But I'm not sure how I should do collisions.

A couple of places have suggested a tilemap with any exposed edges waiting for collisions. The alternative I can see is for me to just build the collision mesh out of individual planes that are snapped-to-vertex, and throw out raytraces from my character to detect when the character is touching anything with a collisionmesh tag.

My biggest concern is speed at runtime.

[NoRegard]

I would use a tilemap where every tile has a collisionbox2D, but I don't know how much that affects performance

It's not a whole lot but it took me all goddamn day long so I'm gonna post it.

Trying to modify [URL="https://www.assetstore.unity3d.com/en/#!/content/15152"]this[/URL] to work in Unity 5.

Results so far:

The blur effect is currently wonky as fuck, also it doesn't take surface roughness or specular color into account yet (neither of which was present in the original package - dammit!)
The code is also incredibly fugly at the moment.

That would require a GameObject for every tile to attach a BoxCollider2D. I've been down that road; it works but its not optimal.

In my current project I use a single mesh to draw all my tiles (divided up with vertices) and map the tile UVs from a single tile atlas texture. Then using the basic tile information (is the tile empty or solid?) I procedurally create several paths on a single PolygonCollider2D.

The mesh build, UV mapping and collision build are all done in a coroutine at the start of the level (doesn't need to be a coroutine, but it allows me to have a loading progress screen).

After building several prototype 2D tile-based games, this method has shown the greatest results.

[BoowmanTech]

I was just using GetComponentInChildren to access an Image component and I remembered how stupid it was built.
Why does it even look at the parent if it says 'InChildren', to get the component from the parent I assume you would use GetComponent, this whole situation is so annoying.

Cheers everyone for the replies

Thanks! Are there any guides on how to achieve this or any places you can recommend to start researching?

I'm also wondering - once you've got your collision mesh, do you still use raycast2D to detect and filter collisions with that mesh?

For my project, I wanted very specific movement mechanics so I tossed out physics and put together my own collisions detection.

I learned the tile map basics from [url=http://youtu.be/bpB4BApnKhM]this[/url] series of tutorials.

Cheers! I was actually looking at that series before but I figured I'd double check I was on the right track.

Working on a small hobby out of my own interest. I'm trying to create new GameObjects as part of procedural generation of a playable open-world universe, which is half-working. Since Unity likes to scream same the three error per elapsed (galaxy) loop at my face.
[t]http://s16.postimg.org/6q79isdj9/screenshot_172.png[/t]

GalaxyObject galaxy = new GalaxyObject();
GalaxySector sector = new GalaxySector();
CelestialObject cbody = new CelestialObject();

These are the three lines the engine spits out about. I've tried changing the right hand of the statement to AddComponent() without any success/verification/feedback from Visual Studio. I have no prefabs ready yet for the moment.

You'll need to create a GameObject first:

GameObject obj = new GameObject();
GalaxyObject galaxy = obj.AddComponent<GalaxyObject>();
// etc...

Its probably wise to just make the prefabs.

That's awesome! So you're using the game engine to lay out tiles, which you can save and then mess with further/add enemies to/etc in Unity proper?

The game has an inline level editor so I can edit the level tiles & entities while I play. I decided to run with this idea because the nature of platformers sometimes requires very precise placement and timing to create a higher difficulty but maintain the ability to actually win.

I also put together my own level format which stores the information in a binary file.

Gotcha. It sounds pretty inense, but it also sounds like something I can work on alongside my general physics, puzzles, etc, until I'm experienced enough to implement something similar in full.
