I have a gameobject in my scene. I want to show the dimension of the gameobject as shown here: So, I created a UI prefab. Now when I am trying to scale the UI (Which us a world UI canvas) prefab. It's not scaling properly! How can I do it? I am trying this now which is indeed not working. Help Needed!
public void setDimension()
{
GameObject g = Instantiate(dimUiPrefab);
BoxCollider b = activeFurniture.GetComponent<BoxCollider>();
Vector2 cameraViewPort =
Camera.main.WorldToViewportPoint(activeFurniture.transform.lossyScale);
g.transform.position = new Vector3(b.transform.position.x/2,b.transform.position.y +2f, b.transform.position.z);
g.GetComponent<RectTransform>().transform.localScale = cameraViewPort;
}
If you are using UGUI,
GameObject g = Instantiate(dimUiPrefab);
RectTransform rectTransform = g.GetComponent<RectTransform>();
// Set size
rectTransform.sizeDelta = new Vector2(width, height);
// Set position
rectTransform.position = new Vector3(posX, posY, posZ);

I created a pin object by script attached it to a sphere object .
using UnityEngine;
public class InstantiateMarkerPin : MonoBehaviour
{
public float Xpos;
public float Ypos;
public float Zpos;
public GameObject gameObjectPinInstantiate;
// Start is called before the first frame update
private void Start()
{
Xpos = 0.09f;
Ypos = 0.50f;
Zpos = 1.1f;
//The original object, where to instantiate, and the orientation of the new object
GameObject marker = (GameObject)Resources.Load("gameObjectPin");
Vector3 location = new Vector3(Xpos, Ypos, Zpos);
Quaternion rotation = Quaternion.Euler(0, 0, 0);
//The object the script is attached to
GameObject world = this.gameObject;
//Instantiate the prefab
gameObjectPinInstantiate = Instantiate(marker, location, rotation, world.transform);
Debug.Log("InstantiateMarkerPin class : Marker Location 2 :X, Y, Z : " + gameObjectPinInstantiate.transform.position);
}
// Update is called once per frame
private void Update()
{
}
}
This script is attached to the sphere Object .My sphere Object have shader material of earth image (globe).
This Instantiated Prefabs (gameObjectPin) on sphere surface appears on scene but not on game screen ,When I select the camera object in the camera preview also this object does not appear .
Scene view
Scene View when camera is selected
I am new to Unity what should I check or correct to appear my created object on the sphere
basically I am trying to add pins to corresponding country and label it .Similar to the globe on this http://kitsdmcc.com/news
Gameobject is created when Play is clicked on the sphere object
When the Pin Object is selected on play mode
Oh now I see it! What you did was only setting its GIZMO via this menu
which is only displayed in the SceneView.
This has nothing to do with the rendering in the GameView but is just a way for easier seeing and finding certain types of objects in the SceneView since usually they would be invisible if not selected.
From the Glossary:
A graphic overlay associated with a GameObject
in a Scene
, and displayed in the Scene View
. Built-in scene
tools such as the move tool are Gizmos
, and you can create custom Gizmos using textures or scripting. Some Gizmos are only drawn when the GameObject is selected, while other Gizmos are drawn by the Editor regardless of which GameObjects
are selected.
As noted in the comments there is no Component at all on your GameObject so nothing is rendered in the Gameview.
Of course now you could enable Gizmos also for the GameView via the Gizmos toggle
but I guess what you rather are trying to achieve is rather rendering that icon in the final App.
You probably would like to use e.g. the SpriteRenderer component here. And simply drag in your Icon to the Sprite property.
You might have to change the Pin Texture's TextureType to Sprite (2D and UI).
In general I would also recommend to Create a Prefab instead of using the Resources folder here.
There are also some changes I would do to your code in general:
public class InstantiateMarkerPin : MonoBehaviour
{
[Header("Settings")]
// directly use a Vector3 for setting the values
// | default value for this field
// | (only valid until changed via Inspector!)
// v
public Vector3 TargetPosition = new Vector3(0.09f, 0.5f, 1.1f);
// Instead of using Resources simply reference the
// created Prefab here
public GameObject gameObjectPinPrefab;
[Header("Outputs")]
public GameObject gameObjectPinInstantiate;
private void Start()
{
// Careful this currently ovewrites any value set via the
// Inspector. Later you will probably want to remove this.
TargetPosition = new Vector3(0.09f, 0.5f, 1.1f);
//As said I would rather use a prefab here and simply reference it above in the field
//gameObjectPinPrefab = (GameObject)Resources.Load("gameObjectPin");
//Instantiate the prefab
gameObjectPinInstantiate = Instantiate(gameObjectPinPrefab, TargetPosition, Quaternion.identity, transform);
Debug.Log("InstantiateMarkerPin class : Marker Location 2 :X, Y, Z : " + gameObjectPinInstantiate.transform.position);
}
// Always remove empty Unity methods
// They are called as messages if they exist
// and only cause unnecessary overhead
}
I was looking for a way to make my gameobject not overlap to the another gameobject but all the solutions are talking about Rigidbody..
when i want to do it in script only without rigidbody, is it possible ? I have a cube with this scale (3,1,1) I make him rotate around itself but i got the overlap problem because his x scale is 3
Is there anyway to make him move and back automatically to avoid the red gameobject?

you can use this method
GameObject myDraggedGO; // parent
private IEnumerator OverLapChecker(float delay)
{
yield return new WaitForSeconds(delay);
Collider2D[] colls = new Collider2D[3];
List<int> nums = new List<int>();
foreach (var tile in myDraggedGO.GetComponentsInChildren<Rigidbody2D>())
{
nums.Add(Physics2D.OverlapCircleNonAlloc(tile.transform.position, 0.5f, colls));
}
if (nums.Contains(2))
{
myDraggedGO.transform.position = _startpositionOnDrag;
}
}
I am trying to draw a line between two UI GameObjects with Linerenderer. In scene mode everything work fine, but in game mode line is invisible. I tried to change Z position of objects but lines are still invisible. Can anyone help me? Thanks in advance
private LineRenderer lineRenderer;
private float counter;
private float dist;
private Vector3 aPos;
private Vector3 bPos;
public Transform origin;
public Transform destination;
public float lineDrawSpeed = 6f;
// Use this for initialization
void Start()
{
lineRenderer = GetComponent<LineRenderer>();
aPos = new Vector3(origin.position.x, origin.position.y, origin.position.z); // Using these to move the lines back
bPos = new Vector3(destination.position.x, destination.position.y, destination.position.z);
lineRenderer.SetPosition(0, aPos);
lineRenderer.SetWidth(3f, 3f);
dist = Vector3.Distance(origin.position, destination.position);
}
// Update is called once per frame
void Update()
{
if (counter < dist)
{
counter += .1f / lineDrawSpeed;
float x = Mathf.Lerp(0, dist, counter);
Vector3 pointA = aPos;
Vector3 pointB = bPos;
Vector3 pointAloneLine = x * Vector3.Normalize(pointB - pointA) + pointA;
lineRenderer.SetPosition(1, pointAloneLine);
}
}
Unless I'm overlooking some logic error in the code you've posted, I think the problem might be with the material.
Generic debugging help for line renderers:
Try setting the color/material of the line renderer:
lineRenderer.sortingOrder = 1;
lineRenderer.material = new Material (Shader.Find ("Sprites/Default"));
lineRenderer.material.color = Color.red;
If that doesn't work, perhaps you need to specify the number of vertexes manually?
mineLaser.SetVertexCount (2);
Finally, if these both don't work, it might just be a logic error; try setting the transforms for the lineRenderer's position to be some predefined value and see if it shows up.
For this specific question:
Ah, so its on a canvas. Assuming you mean the UI canvas, I believe linerenderer is the wrong tool to use in this situation. Check out this question.
One of the answers there suggests to:
just use a panel filled with any color you want and use Height and Width to set the length and the Width of your line
This is impossible in "Screen Space - Overlay" Canvas mode. In that mode UI overlay draws on top of everything in Scene (including LineRenderer, that actually non UI element).
Try to use "Screen Space - Camera" option for your Canvas and "Use World Space" option for you Line Renderer.
I think you must have forgotten to set sorting layer for the line renderer. As this could only be the possible reason if the line is visible in the scene view and not in the game view.
I'm working on my first game in Unity.
I'm trying to draw lines on my game field.
Code:
private void DrawLine(Vector3 start, Vector3 stop, GameObject template)
{
GameObject toInstiateGridLine = template;
GameObject gridLineInstance = Instantiate(toInstiateGridLine, start, Quaternion.identity) as GameObject;
LineRenderer gridLineRenderer = gridLineInstance.GetComponent<LineRenderer>();
gridLineRenderer.SetVertexCount(2);
gridLineRenderer.SetWidth(0.01f, 0.01f);
gridLineRenderer.SetColors(Color.black, Color.black);
gridLineRenderer.SetPosition(0, start);
gridLineRenderer.SetPosition(1, stop);
}
It works with one problem. I get pink lines instead of black that I expect.
Settings of LineRenderer component that has been created in runtime:
You are missing material. Pink is the standard color when material is missing.
LineRenderer gridLineRenderer = gridLineInstance.GetComponent<LineRenderer>();
Material mat = new Material(Shader.Find("Unlit/Texture"));
gridLineRenderer.material = mat;
Or, you can change material color directly. As I consider, calling directly will cause to create standard default material
gridLineRenderer.material.color = Color.white;
I am trying to make a Scrabble word game using a fixed camera, but I have a simple issue.
I add some boxes as game objects and the number of these boxes is the length of the word so if the word is "Fish" we will add 4 boxes dynamically. I did that successfully, but I can't center those boxes in the screen. I tried to add those game objects as children under another game object, then center the parent, but with no effect.
This is my code:
void Start () {
for (int i=0; i<word.Length; i++) {
GameObject LetterSpaceObj = Instantiate(Resources.Load ("LetterSpace", typeof(GameObject))) as GameObject;
LetterSpaceObj.transform.parent = gameObject.transform;
LetterSpaceObj.transform.localPosition = new Vector2(i*1.5f,0.0f);
LetterSpaceObj.name = "LetterSpace-"+count.ToString();
count++;
}
gameObject.transform.position = new Vector2 (0.0f, 0.0f);
}
This image shows you the idea:
I believe your code is working, but the problem is that your first letter is located at your parent object, and then every letter from then on is added to the right. That means that when you center the parent object what you are doing is putting the first letter in the center of the screen.
If you run the game and use the scene view to look at where the parent object is this can confirm this. What you can do instead is that rather than placing the parent at the center of the screen, offset it by an amount equal to the length of the word.
gameObject.transform.position = new Vector2 (-(word.Length / 2.0f) * 1.5f, 0.0f);
You might also want to consider changing some of those constants, such as the 1.5f into variables with names like LetterSize or basing it off the actual prefab so that way any future changes will work automatically.
This is the last solution after some edits to fix this issue.
GameObject LetterSpaceObjRow;
int count = 1;
string word = "Father";
float ObjectXPos;
float LocalScaleX;
void Start () {
for (int i=0; i<word.Length; i++) {
GameObject LetterSpaceObj = Instantiate(Resources.Load ("LetterSpace", typeof(GameObject))) as GameObject;
LocalScaleX = LetterSpaceObj.transform.localScale.x;
ObjectXPos = i*(LocalScaleX+(LocalScaleX/2));
LetterSpaceObj.transform.parent = gameObject.transform;
LetterSpaceObj.transform.localPosition = new Vector2(ObjectXPos,0.0f);
LetterSpaceObj.name = "LetterSpace-"+count.ToString();
count++;
}
gameObject.transform.position = new Vector2 (-(ObjectXPos/2.0f) , 0.0f);
}
