[QUOTE=thomasfn;41692575]I guess you should raycast downwards to find the normal of the surface your character is walking on, then when you set the character's velocity, use the normal to calculate the vector going down the hill.[/QUOTE]

Implemented this, works beautifully. Got it working without any bugs too. Could I get some feedback on the player controller?

I don't see why they wouldn't work, I don't recall garry removing them.
And yes, it works pretty well going down the hill. Nice job.

Friend's decided to make a scrolling shooter in Unity and I decided to help them, this is the progress so far.

Got a little jetpack (with trails that shouldn't be there all the time) jumping, enemies, ect.

There seems to be room for improvement. Like why would you use trails for jetpack, it would be much easier and better looking to use particle systems and then control their emission with a script.

[Asgard]

If you have a CharacterController (and you most likely should), you can easily check if you're on the ground, and then enable/disable the trail/particle emitter.

- Only singleplayer works.
- Haven't started networking yet
- Exit doesn't seem to work
- The scaling with the web player is seems to be based on your screen and not the player..

I'll get back to working on it.

I see what you mean, it works in the embedded web-player if I click it a lot..

I'll always be uploading the latest builds here: [url]http://builds.fridayplay.net/[/url]

[RattSplat]

Latest build - 0.0.5

+ Added NGUI
+ Added menu scene terrain & sounds
+ Added a new singleplayer scene with a few artifacts (the scary stuff)
+ Added new terrain objects to the sp scene
- Fixed the menu not loading other scenes
- Fixed the menu scene's cursor
- Modified sp scene's fog, moonlight (sun), and ambient light
- Modified a few of the artifacts in sp
- Removed herobrine

By the way, listen to the menu sound for ten hours for maximum PTSD.

Im trying to get an isometric camera working, whereby the player can rotate full 360 degrees but the camera always stays in a isometric perspective following the player.
To do this I have thought of the following:

[IMG]http://i.imgur.com/ucGMxBD.png[/IMG]

So the player position game object controls the player and camera position, the player has its own rotation that doesnt affect the camera, and I can achieve very easy camera rotation by rotating the camera target.

Does this sound like a reasonable way of doing it? Or would you suggest a more elegant way?

And that brings me to another question, If i wish to rotate the camera 90 degrees smoothly, what would be the best aproach?

[csharp]
public class CameraRotation : MonoBehaviour {

public float Angle = 45f;
private float rotateOffset = 0;
private bool rotationActive = false;

void Awake()
{
transform.rotation = Quaternion.Euler(0, Mathf.RoundToInt(Angle) , 0);
}

void FixedUpdate () {

if(rotationActive)
{
Angle = Angle + rotateOffset * Time.deltaTime;

//Wrap the angle between 0 and 360
if(Angle > 360f) Angle -= 360f;
if(Angle < 0f) Angle += 360f;
}

//By adding 45 it means the camera always has a rotated offset of 45 degrees, ie: it will be 45, 135, 225, 315
if(Mathf.Round(Angle + 45f) % 90 == 0)
{
rotationActive = false;
rotateOffset = 0f;

Angle = Mathf.RoundToInt( Angle );
}

transform.rotation = Quaternion.Euler(0, Mathf.RoundToInt(Angle) , 0);
}

void Update()
{
if(Input.GetKeyDown(KeyCode.Q))
{
rotateOffset = 90f;
rotationActive = true;
}
if(Input.GetKeyDown(KeyCode.E))
{
rotateOffset = -90f;
rotationActive = true;
}
}
}
[/csharp]
Is what I currently have, however its dangerous because if Angle changes to a value that means Mathf.Round(Angle + 45f) % 90 != 0 then it could rotate for ever

[Falez]

CameraTarget (and its child) doesn't have to be parented to PlayerPosition. You might want to consider creating a CameraFollow script that follows the target instead. With that you could make cutscenes (e.g. player using a lever moves the camera towards the door it opens for a short while)
[img]https://dl.dropboxusercontent.com/u/7422512/Unity3D/oneway.PNG[/img]

For smoothness:
Use Quaternion.RotateTowards.

[unity]https://dl.dropboxusercontent.com/u/7422512/Unity3D/test/test.unity3d[/unity]

CameraRotate.cs (Put this in CameraTarget)

using UnityEngine;
using System.Collections;

public class CameraRotate : MonoBehaviour {
	
	public float speed = 10;
	
	private Quaternion to;
	
	// Use this for initialization
	void Start () {
		transform.rotation = Quaternion.Euler(0, 35.264f, 0);
		to = transform.rotation;
	}
	
	void OnGUI()
	{
		GUI.Label(new Rect(10,10, 250, 30), "Y Rotate Speed: "+speed.ToString());
		
		GUI.Label(new Rect(10,45,50,30), "0");
		GUI.Label(new Rect(230,45,50,30), "300");
		speed = GUI.HorizontalSlider (new Rect (25, 50, 200, 30), speed, 0, 300);
	}
	
	private int a = 0;
	
	// Update is called once per frame
	void Update () 
	{
		float step = speed * Time.deltaTime;
		
		if(Input.GetKeyDown(KeyCode.Q))
		{
			a++;
			if(a > 3)
				a = 0;
		
			to = Quaternion.Euler(0, 35.264f+(90*a), 0);
		}
		if(Input.GetKeyDown(KeyCode.E))
		{
			a--;
			if(a < 0)
				a = 3;
			
			to = Quaternion.Euler(0, 35.264f+(90*a), 0);
		}
		
		transform.rotation = Quaternion.RotateTowards(transform.rotation, to, step);
	}
}

Finally found a Unity UI library that doesn't totally suck dick, and doesn't do things in an ass backwards way. Finally can fuck NGUI the fuck off.

Literally thank you so much. I dreaded the fact that I eventually had to get NGUI because it was the only decent one out on the market, but this is so much better.

Go through the official tutorials first. They will run you through most things you need to do better than most tutorials. They game tutorial they have there is good as well, but there are more varied tutorials on the internet. These are just the best for explaining the basics of unity and the components.

I've been playing around with Unity a lot after reading this thread, I'm a rather shitty programmer but I'm finding C# easy enough to work with. I've just been following some tutorials and stuff for now and I'm finding it rather fun, I've always wanted to make a game myself but I've really only made little mods or maps of other games so this is a good learning experience.

[QUOTE=Richy19;41814237]Im trying to get an isometric camera working, whereby the player can rotate full 360 degrees but the camera always stays in a isometric perspective following the player.

I'm probably a bit late but whatever.

I was trying to make an RTS styled game before with a similar camera. As I said I'm rather bad at programming but after following some tutorials and fiddling around with the code, I got a mouse controlled camera that can move and rotate around a point in a somewhat crappy, glitchy way.

(Press ctrl + rmb to rotate, scroll to zoom in/out, and move the mouse to the sides to move the camera)

[unity]https://dl.dropboxusercontent.com/u/64863030/TestRun.unity3d[/unity]

This is what the camera has:
[csharp]
using UnityEngine;
using System.Collections;

// The in-game camera controls
public class CameraGame : MonoBehaviour
{
// Zoom stuff
public float ZoomLevel = 6;
public float ZoomMax = 11;
public float ZoomMin = 2;
public float MinCameraHeight = 10;
public float MaxCameraHeight = 40;
public float ZoomSpeed = 5.5f;

// LateUpdate is called after every frame
void LateUpdate ()
{
CameraZoom();
}

// Zooming in and out with the mouse wheel
private void CameraZoom ()
{
// Zoom in
if(Input.GetAxis("Mouse ScrollWheel") < 0 && ZoomLevel <= ZoomMax)
{
ZoomLevel += ZoomSpeed;
}
// Zoom out
else if(Input.GetAxis("Mouse ScrollWheel") > 0 && ZoomLevel >= ZoomMin)
{
ZoomLevel -= ZoomSpeed;
}
camera.orthographicSize = ZoomLevel;
}
}
[/csharp]

And this is what the target it's parented to has:
[csharp]
using UnityEngine;
using System.Collections;

public class CameraFocus : MonoBehaviour
{

// Movement stuff
public float ScrollSpeed = 25;
public float ScrollWidth = 15;

void LateUpdate ()
{
CameraMove();
CameraRotate();
}

// Detecting mouse movement
private void CameraMove ()
{
float xpos = Input.mousePosition.x;
float ypos = Input.mousePosition.y;
Vector3 movement = new Vector3(0,0,0);

// As long as the left mouse button & ctrl is not pressed
if((Input.GetKey(KeyCode.LeftControl) || Input.GetKey(KeyCode.RightControl)) == false)
{
// Horizontal camera movement
if(xpos >= 0 && xpos < ScrollWidth || Input.GetKey(KeyCode.D))
{
movement.x -= ScrollSpeed;
}
else if(xpos <= Screen.width && xpos > Screen.width - ScrollWidth || Input.GetKey(KeyCode.A))
{
movement.x += ScrollSpeed;
}

// Vertical camera movement
if(ypos >= 0 && ypos < ScrollWidth || Input.GetKey(KeyCode.S))
{
movement.z -= ScrollSpeed;
}
else if(ypos <= Screen.height && ypos > Screen.height - ScrollWidth || Input.GetKey(KeyCode.W))
{
movement.z += ScrollSpeed;
}
}

// Camera movment and locking y axis
movement = transform.TransformDirection(movement);
movement.y = 0;

// Calculate cameraFocus position based on received input
Vector3 origin = transform.position;
Vector3 destination = origin;
destination.x += movement.x;
destination.y += movement.y;
destination.z += movement.z;

// If a change in position is detected, preform the necessary update
if(destination != origin)
{
transform.position = Vector3.MoveTowards(origin, destination,
Time.deltaTime * ScrollSpeed);
}
}

// Rotate stuff
public float RotateAmountx = 0.0f;
public float RotateSpeed = 2000;
public float RotateWidth = 10000;

private void CameraRotate ()
{
// Getting mouse position
float xpos = Input.mousePosition.x;

if((Input.GetKey(KeyCode.LeftControl) || Input.GetKey(KeyCode.RightControl)) && Input.GetMouseButton(1))
{
RotateAmountx = xpos;

}

transform.rotation = Quaternion.Euler (0, RotateAmountx, 0);
}
}
[/csharp]

I don't know if this code is any good or not, but I can say that the problem with my method is that the rotation will "jump" to the point you click at. But I'm sure there is an easy way to fix to that.

If I want to get into developing little minigames with unity, where do I start?
I thought asking here was a good idea since out there on the internet, there are out dated stuff.

Also, I plan on developing with javascript since I dont know c#

[Falez]

Start by making simple games. I think I posted this [url=http://forum.unity3d.com/threads/26785-Unity-Jump-Start-Video-Tutorials]link[/url] twice in this thread (not including this post). It guides you to implement the core mechanics (movement, dumb AI, shooting, collision, score, game states) of Space Invader in Unity, and teaches you the basic flow on using Unity. The tutorial is in Javascript.

What you really want from the tutorial is to learn the workflow of Unity, anyway.

What it teaches you:
