please help me
I want to move my character and jump but whenever I press play my characters parts like the hand and legs etc. keeps separating I want then to be intact and move and jump .btw they are in dynamic
Use Joints to create connections between physical objects.
Each physical object ceases to depend on the hierarchy.
If you do not need physics, then you can make objects kinematic or remove physics altogether.

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)).
For my game, the player character requires to climb up and down ladders those are placed in the gameplay area.
At present, I can able to climb up for my player character to climb down at present I don't have anyway. Because platform box collider applied with platform effector, so for the climb up, effector does not create any problem but now after reaching the top, it becomes solid platform so now I can't able to move downside.
For climbing up, I have followed this tutorial: How To Make 2D Ladders In Unity - Easy Tutorial
I am looking to implement some physics so I can reach downside to the ladder after reaching top.
You need 2 boolean variables isClimbingUp and isClimbingDown which depend on pressed key and a second ray, which will check -Vector2.up direction. Then just add one more 'else if' statement for down direction.
Yes, I have managed to solve this, and the game is published in the stores.
You can check using the below link:
Humpty Trumpty's Border Wall
This is my overall physics setup for the stair:
I have applied a trigger collider to my stair object and disable player gravity scale when the player within the stair.
Then after within the trigger enter and exist, I have done this:
Physics2D.IgnoreCollision(m_CapsuleCollider, myStair.platformCollider, false);
Disable collision between player and platform colliders when the player is within the stair.
I don't think, Platform Effect 2D becomes useful to me in this process but I didn't remove this to remain in the safer side.
So you have to keep a reference of the platform object which is attached to Stair.
I hope you will get a general idea to solve this problem.
I want to create a circular room in a 2D level. How can I handle this problem?
My thought process was to break the level into chunks and move their position depending on where the player currently is. This would allow the level to wrap around depending on where the player travels. I can do this manually with each part but i'm looking for a better solution that can handle this programatically. I'm open to better ways to solve this problem as well.
Is the space 2D? if so, you could place two invisible colliders at the extremities of the room (one at the beginning and one at the end), and change the player's position when he collides with them. To ensure that the transition is smooth, place them a little outside of the camera space: the player won't be rendered during transition, and you would obtain a teleport effect from side to side.
As another suggestion, you can lock the player to being in the center chunk with a camera just showing that chunk. Everytime he gets through a collider on the end or the start of the middle platform you delete the opposite side platform and place it in the far end of the platform the player is now seeing, effectively making the new platform as the middle one.
Long-winded question out of the way, I'll provide a diagram of what I am going for:
The red square represents the character, the blue rectangle represents the camera, the green dot represents the center of the "stage", and the black circle is the stage itself.
What I desire is to essentially lock the player's movement around the "center" of the stage, so that anytime you move left or right you are more or less rotating around said center. However, I also want the player to be able to move forwards and backwards to/from the center as well. Keep in mind I want the camera to always stay directly behind the player. I have tried many different methods, and the latest is the following:
I took a default actor, attached a spring arm, attached a child actor to that (gets possessed to become the playable character), attached another spring arm, and finally the camera to that. I then added the blueprint code to the first spring arm so that it was the one being controlled by the left/right controls. However, upon hitting play, the only thing that moves is the camera, and it can only move forwards and backwards.
I'm admittedly pretty new to Unreal Blueprints, so any help would be appreciated.
Alright, I figured it out.
Here's the setup needed if anyone else wants something similar.
For the player themselves, you'll need something like this:
The important thing is to center the root mesh where you want to rotate around. The spring arm's target arm length will be affected for the player mesh movement, giving the illusion you are physically moving the character. The second spring arm isn't necessary unless you wish to have more control over the camera to player distance.
For the rotation Blueprint, you'll need this:
The target is whatever you named the root mesh. (Mine was called Center) Drag and drop it from the hierarchy.
For the forward/backward movement, you'll need this:
The target is what you named the spring arm. (I left mine as the default "SpringArm") Again, just drag and drop it from the hierarchy.
Adjustments in Project Settings:
Yes, my inputs are backwards from what you'd think. I felt it was quicker just to reverse the inputs instead of adjusting whatever was causing the movement to be backwards in the first place. (It's probably just the sphere orientation.) Also, you'll notice I have the w and s inputs set to 5 or -5 instead of 1 or -1. This is due to the fact the movement was slow otherwise. I'm sure there's a fix that doesn't involve changing the input axis scale, but honestly I won't really have a reason to alter the values at any point in my project. If it ever comes up where I do need to, I'm sure there's a bypass to change the values from within blueprints anyways.
End result:

If I remember correctly, child actor components are a bit different from other components in that they are transformation independent, that is they do not update their transformation when their parent component moves around.
I find it a bit strange that you would separate your player actor and the camera component. Normally, the player "pawn" contains the mesh and camera components for one player.
I would suggest you do the following:
Create a player actor (e.g. a "pawn" or "character" class)
Create the following component hierarchy:
Root Scene -> Spring arm -> Skeletal or static mesh -> spring arm -> camera
Your root scene is the green center in your drawing. You can then basically use the blueprint you already have to rotate and move your player.
I am having a problem with a game I am currently developing in Swift. I have blocks that turn static upon hitting each other or the ground and my hero sprite cant go through them so instead he just goes under them when enough force is applied. Obviously I dont want this and simply want him to not be able to move any more left or right when he comes in contact with a block from the right or left side.
Assuming your hero moving is an action you programmed, you can use .stopAllActions() to make him stop moving when he collides with one of the blocks.
