I am making a game and player has to reach at specific destination.
I want to show side game map to guide him the way that where is he now and where he has to go. Just like GTA and other game where a side map always appear in any screen corner which guide player.
I don't have any idea how can I do this I checked it on google but maybe I'm missing the appropriate words for searching.
currently I made a photo of my scene and just showing it on right bottom corner of my game screen. how can I place current user position and destination position and change it accordingly as player move??
public Texture mapTexture;
void OnGUI() {
GUI.DrawTexture(new Rect(Screen.width - 200, Screen.height-200, 200, 200),mapTexture);
}
Thanks to google and #Serlite.
using this youtube video and unity3d Web.
I made side camera (minimap camera) parent to my player and set the Normalized View Port Rect property setting and Al-hamdu-lillah its working:)!! "" camera setting

I have been successfully building and running a Unity 2D game, but started receiving a Blue Screen during one of my operations. Specifically, when I close a popup and remove all of its child Game Objects, the entire Game Screen turns dark blue (the default background color of the main camera). The music for the game still plays and clicks are still registered if you click in the right area (I can still press the back button, just can't see it).
If I remove 1 gameobject, this problem doesn't come up. But once I have to remove 2 game objects, the entire screen turns blue.
This is my function for removing my game object in case it helps, which works perfectly when it comes to actually removing the gameObjects correctly (game objects to be removed are created from prefabs). I think the problem may be with the camera for some reason, but I have no clue as to why it happens on this function.
public void Remove(int index)
{
float toggleWidth = toggle.GetComponent<RectTransform>().sizeDelta.x;
DestroyImmediate(scrollSnap.pagination.transform.GetChild(scrollSnap.NumberOfPanels - 1).gameObject);
scrollSnap.Remove(index);
scrollSnap.pagination.transform.position += new Vector3(toggleWidth / 2f, 0, 0);
}
I don't receive any errors or warnings in the console. Just a blue screen once more than one GameObject is removed
EDIT:
Turns out my main Canvas's planeDistance was being changed from 100 to 3200. I still have no clue as to why this change occurred...but for anyone else having a similar issue with a dark blue screen appearing in the middle or start of their game, then please check the values your canvas and camera in the Inspector. Simply controlling the planeDistance did the trick for me!
Made a new scene next to the sample scene when i started my sprite learning game. Forgot all about that.
When I had to publish it, In the Build Settings, I had the wrong scene selected. So It published an empty scene instead of my game.
I solved it by putting game in 3d mode and realized that the camera is positioned very far from the sprites, just change the z-axis and again go to 2d mode.
Just Move your camera in Z-axis position, it could be too far from object or it is behind the object, you can also check it by 3D mode the check the object position and change it in positive and negative values.
Scenes:
1.Splash,
one image with the IEnumerator Start() code as described below.
2.Menu,
Canvas UI with a few buttons and a some gameobjects in the scene as background. Camera has a tonemapping and depth of field script.
Stats: Batches 96, tris 20.4k, 41.5k
3.Main
Main scene of the game.
Bug, happend on android device and on pc in the editor:
1.Splash scene loads the menu scene using:
IEnumerator Start()
{
AsyncOperation async = SceneManager.LoadSceneAsync("Menu");
while (!async.isDone)
{
yield return null;
}
}
2.The canvas UI of the Menu scene appears with a black background, the gameobjects in the scene are not visible, for a few seconds.
3.The canvas UI + the scene is visible.
Same bug happens when the Menu scene is loaded from the Main scene.
Unity version = 2017.3.0f3
Using vuforia in the main scene.
EDIT:
I disabled all the objects and camera effects in the Menu scene except for a plane and the canvas, the canvas still appears a few seconds before the plane.
To describe the bug better, the camera seems to active a second after the canvas UI is shown.
EDIT2:
I created a new camera in the menu scene and the problem still persists.
I found my fix by adding an AR camera to the scene and disabling the the VuforiaBehavior component which was making the black screen when the scene was loading.
In my case, I just had checked Split Application Binary in Publishing settings to be able to upload my game to Play Store. (Play Store does not accept apk files to be bigger than 100mb, so you split your big apk into a smaller apk & a obb file)
However, if you do that, you need to put both your .apk and .obb files to specific folders in your phone, when you are manually testing the game.
.obb needs to be in a specifically named folder, with a specific name, as explained here: http://graphicdna.blogspot.com/2017/06/manually-copying-unitys-apk-and-obb.html
Shortly, name should be in the format:
main.[FIRST_PART_OF_VERSION_NUMBER].[PACKAGE_NAME].obb
Where [FIRST_PART_OF_VERSION_NUMBER] is the highest digit of the version number you can find in the Player Settings. For instance, if your version is 1.0.0, [FIRST_PART_OF_VERSION_NUMBER] is 1.
And [PACKAGE_NAME] is the package name specified in the same screen, right above the version number.
The game will expect to find that OBB file in a location like:
[INSTALL_LOCATION]\Android\obb\[PACKAGE_NAME]
Where [PACKAGE_NAME] is the same value described above, and INSTALL_LOCATION refers to whether the game is installed in the internal memory or the external SD-Card (this depends on your own settings).
I´m kinda new to Unity 3D and C#. Also i´m not exactly sure how Kudans arbitrary tracking solution works in detail. I´m currently using the Unity Kudan SDK to build a VR positional tracking solution, atleast i will try it. Now my plan is:
Whenever the mesh is leaving the screen, i want to freeze it´s position and find new feature points (the "place markerless object" button is doing this: Find new feature point and place a mesh).
Once it found new feature points (which should be a matter of milliseconds) it defreezes the position of the mesh and use the new feature points to further alter it´s position.
The "find new feature point" idea is necessary because whenever the mesh and the old feature points are leaving the screen, tracking will get very inaccurate.
I already tried this in SampleApp.cs:
bool VRSignal;
public void Start()
{
//Get Bools from "KudanTracker"
GameObject g = GameObject.Find("Kudan Camera");
KudanTracker bScript = g.GetComponent<KudanTracker>();
bool VRSignal = bScript.ArbiTrackIsTracking();
}
public void Update()
{
if(VRSignal == false)
{
// from the floor placer.
Vector3 floorPosition; // The current position in 3D space of the floor
Quaternion floorOrientation; // The current orientation of the floor in 3D space, relative to the device
_kudanTracker.FloorPlaceGetPose(out floorPosition, out floorOrientation); // Gets the position and orientation of the floor and assigns the referenced Vector3 and Quaternion those values
_kudanTracker.ArbiTrackStart(floorPosition, floorOrientation); // Starts markerless tracking based upon the given floor position and orientations
}
}
But now it won´t track properly track anymore, also i´m pretty sure ArbiTrackIsTracking() won´t be the solution for that because it won´t lose tracking when the mesh left the screen.
Do you have any idea to solve this problem?
if I understand well, you want change position of 3d model with trigger as soon as your 3d model disappear of the screen.
And you are right, ArbiTrackIsTracking() remain true even if the 3d model go out the screen because if you move again your screen around the 3d model, the 3d model will be always tracked.
But if you move too much your smartphone logically the tracking stops.
My idea for your issue is to get the position of your 3d model markerless transform driver, because the 3d model moves in function the position and orientation of your smartphone to track.
So you can take the position of the moment where your 3d model begin to be tracked.
Then you give a value who will correspond to the difference of first and last position saved.
And if this difference is get, you stop the tracking with arbitrack stop.
if you have another question you can ask on my twitter account #ModeLolito I could answer faster.
And you can watch my youtube channel to see my works on kudan

I'll explain my issue (My English is a little lame sorry).
I have a Player ( Camera) who is able to move in a Unity Scene. In this scene there is some GameObjects. Those GameObjects May be too far for the camera to see. What I want to achieve is to have an UI Image that appear in the direction of every objects. Even if the objects are too far.
Example : The player stand at a position. In front of him there is an object that is far. I want to have a GUI on screen who says "there is an object at 200 m ". If there is an object behind him I dont want anything to appear. But if he turns back, it will appear cause the player is in the direction of the said GameObject.
I really hope I made myself clear. Please tell me if you need any further explanations. Thank You community !
Answering to an old question of myself :
Here's what I did :
if (markIsOp) //Check if it's worth calculating
{
//Calculs the Viewport Position of the object
Vector3 ViewportPosition = Camera.main.WorldToViewportPoint (transform.position);
//Calculs it's Unity Canvas position (O.5f because UI anchor is middle)
Vector2 WorldObject_ScreenPosition = new Vector2 (
((ViewportPosition.x * mainCanvasRect.sizeDelta.x) - (mainCanvasRect.sizeDelta.x * 0.5f)),
((ViewportPosition.y * mainCanvasRect.sizeDelta.y) - (mainCanvasRect.sizeDelta.y * 0.5f)));
//Making sure it's forward (markRect is my UI Element's RectTransform)
if (ViewportPosition.z > 0)
markRect.anchoredPosition = WorldObject_ScreenPosition;
}
Thank you for your responses.
Have a nice one
You could as well use Camera.WorldToScreenPoint to calculate the "UI-Position" of your GameObjects and then calculate the distance using z-Coordinates of Gameobjects and Camera.
Use a raycast from the player to the game object, and calculate the difference.
I am trying to achieve an effect similar to one of the cardboard app examples that Google has put out with their cardboard app called the 'exhibit'. I have a 3D object that I want to rotate using device orientation control. Right now with just the device orientation control, I can view the 3D object but when I turn around, the camera rotates (it seems) causing the object to fall out of view until I turn all the way back around to where it was in the beginning. In other words the camera seems to rotate in its axis as I look around. What I want is to be able to rotate the object as I turn around.
Kinda like this example http://threejs.org/examples/#misc_controls_orbit except I want to rotate using device orientation control.
Any idea how I can incorporate this feature?
Thank you for your assistance.
The answer to my own question for future seekers is to replace camera in
controls = new THREE.DeviceOrientationControls(camera, true);
with the 3D object you are trying to rotate.
