How to use and adjust 2D collider in Unity

In this video we will talk about how to adjust the shape of a 2d collider in Unity.
Tilemaps in Unity allows us to quickly design levels for our games. The problem is usually with the colliders that our tiles generate. The automatically created collider doesn't always matches what we had in mind. Lucky for us there is a simple way to tweak it. Let me show you how in this video 😉

Man, I am so glad you made this tutorial, I was trying to find a way to adjust the spikes colliders in my game but I couldn't find any helpful videos. Thanks a lot and keep the good work!

Nice tutorial! Thanks! Now i'm trying to figure out how to make the top part of the trees and bushes with no collision .

@SunnyValleyStudio 7 месяцев назад

You can always create your colliders as separate Tilemap and instead of using tree tile as collision shape use something else. In general think about layering multiple tilemaps together.

Hey, are you still planning to release part 2? The collision and render order based on the direction the player is approaching from is what's been a pain in my side with unity tilemaps for the longest time. Really looking forward to seeing how you solved that!

Great video. Small thing incase anyone else have this issue. I had to Remove: Composite Collider 2D Rigidbody2D Tilemap Collider2D to force a regeneration of the collider after editing the sprites Physical Shape. Disabling and reenabling the component didn't work for me.

Strange. Which Unity version are you using? Maybe they have changed something. Feel free to join our discord (discord.gg/RQEtYHz) and let me know since I can sometimes forget to answer comments 🙂

@JonelKingas 8 месяцев назад

@@SunnyValleyStudio It works now, i had to update aseprite importer, it worked on PNG files but not aseprite files, cause I did some research and found out only recently that there was a new version that turned on custom physics shape support on it.

When I go into wireframe mode it does not show up and then you walk through the tile map thing that I made

@SunnyValleyStudio Год назад

Do you have Gizmos toggle on? It is the first icon on the top right of the scene view. Here is more info about it docs.unity3d.com/Manual/GizmosMenu.html

@triple3204 Год назад

Thank you! It works now :)

@MarkWaner Год назад

But what if stairs were 3 tiles wide? Can we make it so that some sprites do not generate a collider?

@SunnyValleyStudio Год назад

If you don't add a tilemap collider or make a secondary tilemap with no collider you will have stairs that don't collide with anything.

@gambit1637 2 года назад

I tried to use Composite Collider and it didnt collide at all, only top and bottom was added to collision. So i stayed in Collider 2D.

@SunnyValleyStudio 2 года назад

Hey! It is just for the purpose of optimization. Check out the documentation to learn more about it docs.unity3d.com/Manual/class-CompositeCollider2D.html

@academiadoscoins9034 Год назад

Help me friend! I'm going crazy with the collisions in Tilemap. I have a cannon that shoots a bullet at the walls of a tilemap. The bullet bounces like a pool table. But the collison.transform.position and then the tilemap.WorldToCell(position) gives me the cell in the wrong grid. It doesn't return the cell where the collision occurred. I can even change the Vector3Int, but in collisions in the corner (diagonal) it does not return the correct tile.

@SunnyValleyStudio Год назад

Maybe this can help discussions.unity.com/t/how-to-detect-on-which-exact-tile-a-collision-happened/216779

It didn't. Actually the forum answer is incomplete and doesn't have any examples

@Gendon- 2 года назад

I can't remove collider from sprite editor, how to remove it?

@SunnyValleyStudio 2 года назад

I am pretty sure that you can select each point and click DELETE or there might be in the top options / parameters bar to add / remove colliders.

@jackpp8337 2 года назад

if player Near the wall foot , the bullet gets caught in the wall .How do you fix that

@SunnyValleyStudio 2 года назад

Hey! I am not certain if I understand correctly but basic solution is always to tweak things until they work together. You bullet can have a separate smaller collider to collide with walls or I guess your wall can have a smaller collider (although its a lot of work). screenshots
