I am creating a 2D grid based game in Unity. I am using Tile maps for background (one grid and two tile maps).
On the first tile map I have the background (like grass) and on the second one I have things I add, like a hole in the ground. Now I add game objects to the scene (a sprite tree). I have two BoxCollider2D on the tree, first one is just a small one at the bottom of the tree and the other one covers the whole tree but is set as trigger (I have a script that automatically fades out the tree when user is behind it).
The problem is that the user keeps getting stuck at the collider (I think) at the bottom of the tree. It works from some angles. I tried creating a small 2D square too and sometimes I get stuck to that too. What am I missing?
I have added a custom material that has friction set to 0 on both the Player and the tree.
I don't know if it is relevant but the tree is quite big so I had to set its size to 0.5 instead of 1.
remove the interaction between the player and the tree, see in project setting, modify the script to work with a raycast
or just make the tree collider a Trigger..

I've a simple project with a few objects.
I tried to move "player" object (Marked in the picture) to top of other objects but still it is in backward!
How to bring it to forward?
We need some more information to give an accurate answer for your exact situation, such as the properties of the Sprite Renderer (assuming Player is a sprite) and the properties of your Canvas and UI elements (especially if it is a world space canvas), and any code you might be using to instantiate, render, or move the player.
In general though, for sprites, you can bring a sprite in front of other sprites by either changing the Z value of the transform (negative Z is closer to the camera), or better by changing the Order in Layer of the player sprite renderer, and make sure it is in a layer that is in front of the other sprites.
As for Canvas UI elements, the element at the bottom of the hierarchy will be rendered last, meaning it will show in front of everything. Think of a UI hierarchy like stacking papers on top of each other. The first piece of paper placed down will be at the bottom of the pile.
I'm trying to make a game and I need to render a tileMap that the player can move but also modify its size.
First I created it programmatically, filled it randomly and it worked perfectly fine. As a result I designed a custom tileMap in the scene editor and I used it in code so that the player is able to move it or change its size and there I have a problem.
The tileMap is a 48x48 tileMap but if the intersection between the 24 and 25 column touch the left side of the screen, the whole tileMap (even the part on screen) disappear and if I bring it back on the screen (by selecting the invisible position where it was) and drag it back on the right it reappears.
The only solution that I found is to design the whole tileMap programmatically but this will take quite a long amount of time. Has anyone found how to tackle this issue ?
(changing shouldCullNonVisibleNodes and transparency has no effect)

I want to remove mesh of object when user click on object and also remove its collider to make another object fall from that removed mesh area...
I am using unity since last month so I don't have much experience and knowledge, please help me...
Creating the destructable ground particles
One way to achieve whats shown in the gif is by creating a prefab of e.g. a circle collider that is instantiated in the area of where the dirt is in your gif. It acts as a "ground particle" and keeps the objects above itself.
You instantiate a lot of them in the area so it acts as a big collider although it is actually a whole array of smaller colliders.
Implementing the interaction logic and deactivating the ground particles
Ater that you implement the functionality of dragging the mouse over the ground particles, removing them. That is also not difficult. Shoot raycasts into the screen at the postition of the mouse (remember to use Camera.ScreenToWorldPoint) and get the collision information (confer to https://docs.unity3d.com/ScriptReference/Collider2D.Raycast.html). With the collision information you can get the reference to the instance of your ground particle(raycasthit.other.gameobject) which is then disabled through script(gameobject.setActive(false)).
As you can see in the included video the player falls over the floortile till the outer edge of the floor. Instead it should stop at the inner edge of the tile so it looks like its standing ontop of the tile. Can anyone help? I cant find anything on the internet regarding my issue.
Im sorry if this is a easy fix. Im a beginner. This for a school project :)

Edit: I went back to the tile palette and redrew the level. This time selecting the game object + bitmap again. Now it works. Probably the reason why it didn't work was that when I drew the level I had not added Tilemap Collider 2D and Composite Collider 2D. Now redrawing with those 2 components added it works as it should!
The problem is with your tile map collider. Instead of using this, set empty game objects as children of the objects that make up the . Then, add BoxCollider2Ds to each one, and add scale them to fit the map. If that doesn’t work, then it is either a problem with the rigidbody, or the box collider, make sure that all of the settings are set to default, then slowly change them back, and you will discover what is causing the problem. Then you can comment on this post what variable changed it.
Your issue is the Composite Collider. The docs specify that they
do not define an inherent shape. Instead, it merges the shapes of any
Box Collider 2D or Polygon Collider 2D that you set it up to use
When you attach a BoxCollider2D or PolygonCollider2D, there is a check box on them that specifies Used by Composite. When checking this box, other fields will disappear as they are now controlled by the CompositeCollider.
To use this collider, make a new object that will hold all your other colliders or make a few that hold sections of your map. Give this new parent object a CompositeCollider2D and give all the children BoxCollider2D or PolygonCollider2D. After this, make sure to check the box Used by Composite on the children Colliders.
Edit: Sorry just saw you were using a Tilemap. Just make the CompositeCollider a parent of your Tilemap while keeping the Used by Composite checked.
Edit 2: I am not too familiar with Tilemaps with Composite Colliders, but one other solution you can try before re-childing is changing the Geometry Type field on your CompositeCollider from Polygons to Outlines.
I would like to move a tile with drag and drop in Unity 2D. The tile is a sprite. The scene is an 'Unblock me' or 'Blocked in' like gameplay.
Because the tiles in real life correspond to physical objects it seemed be to a good idea to model them with colliders and rigidbody. The border of the table surrunded with invisible colliders. I hoped these will constrain the moves of the tiles realistic, when the player moves them.
Then I implemented a simple (mouse based) drag and drop behavior which is worked perfectly except the moved tile penetrates to other tiles and the border, and sometimes jumps over them. Then I learned if I am overriding physics by explicitly setting transforms position (which I do exactly in my drag and drop implementation), this will happen. OK I accept, I should set only forces, ect. on rigidbody never directly the position.
Now the question:
I am stuck here. I still want to drag and drop like user experience, and some realistic visual result. When in the real life a player moves a tile, it seems it is "glued" to its finger. How can I achieve this (ot at least similar) with just applying forces? Any suggestions or point similar existing sample/blog code?
(I know as a backup plan I can omit all the physics and constrain the tile positions by code, and create some tweens to move the tiles. Is the real solution (what I am asking for) so complicated I should vote on this backup plan?)
Edit
According to comments I've added a video:
There is nothing wrong with the way you are manipulating your dragging. The beauty of developing is being able to do things in your own way. If it works for your game, then don't fret.
Now, i recommend:
Create a new physic material. Assets > Create > Physic Material
Set your new physic material inspector settings both to 0
Attach the physic material to all your wall object colliders. This should allow for your object being dragged to move smoothly against the walls without chopping.
Do a check to see if your mouse is over another collider. If so, then stop the movement in that direction.
Since your movements seem to always be on a single axis, on collision, tell your object to snap to the edge of the wall object. You know the Wall position and scales, also you have the position and scales of the object being dragged. with that you can write a function that will offset it to the correct position when the collision occurs.
Let me know if any of that works out :P
