click here for gif show of what I want
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'm new with unity, this is my first project. I want to make a racing game, as we know unity has that kind of game on it's standard assets package.
Now, my problem is I try to improve that standard packages by combining my own ground design and unity's standard assets car script.
First Position:
I've done with rebuild and combining those elements, then when I play the game then the car's position changes. I don't have any idea about what happens. This is the result :
Can somebody here help find out the solution? Thank you
As per the images you show it seems like the car sinks a little bit in the ground. This can happens because the car has got a rigidbody and when you press play it is affected by the gravity of the scene, so it falls until meeting another collider, in this case the one of the ground (If the ground doesn't fall as well is because it hasn't got a rigidbody or is static).
What you should do is to mark the collider of the ground as static (in case it wasn't static already) and then reshape it, so its size matches with the shape of the ground. The other option is that the car has got a collider just covering to the point of the wheels until it sinks.
Check the shape of both colliders (car and ground) and ensure they cover entirely each game object.
I am trying to hit a ball using a golf club. My golf club has three components (three game objects: handle, shaft and head as shown in the first attached image). Head gameobject's inspector can be seen in the another attached image.
To hit the golf ball, we need a collider. So I put a Capsule Collider at head game object. But I don't see any collider at head gameobject.
The head is shown in the last image.
Why I can't put Capsule Collider at the object?
EDIT:
Thanks for the reply.
I increased the radius but still the same.
I placed a Quad in the scene and put Mesh collider onto it (called AW52Collider). Please see in the
first image. We can see the collider clearly.
But I did the same thing to Club head, as it is also a game object I should be able to put a Mesh collider. But I don't see anything. Why?
Please see in the second image.
One more thing I don't understand is when I put AW52Collider inside Club Head object, I don't see AW52Collider also. Why? Please see in the third image.
Increase the size of your collider, those values do not look like you should see the gizmos at all. Best would be to reset the collider to its default values and then play with them until you are happy.
It is best practice to create a child object with colliders on it. The reason is the placement of the collider. The collider is always centered around the pivot point of a GameObject. But you probably want to move your collider freely or disable a group of colliders manually for testing (or optimization) purposes. Also consider that an object with multiple small colliders as child objects is considered one big collider (rigidbody wise). Source (Compound Colliders)
Just enable Gizmos button and you'll find your capsule collider.
See this picture to know exactly where to find it:
(It's in the toolbar below the Scene tab)
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
I'm new to Unity and the is working on a personal project. In the following picture, you can see a blue plane in the middle, I want to use it as a ice plane and there should be no friction when user is walking on it. In another way, if I press 'w', the object should move forward until it hits an object. I know there's a built-in function called physic material, but it works only when the plane is tilt at some angle so that the object will slide down from the top to the bottom, but if the plane is placed in a horizontal level it will not work. Anybody has any suggestions for it, thanks.
Answering from my phone and off the top of my head, but look at using input.getaxisraw() to get your direction data then add forces. use triggers to stop the movement when you reach a trigger on another object. There were some good tutorials on Collisions and triggers on unity tutorials. To elaborate more, you can add colliders to the objects that you want your player object to interact with physically. So for your player object you can add code like:
OnTriggerEnter(collider c) {
// stop movement
}
