![]() Grid: Generates a Collider shape based on the shape of the Grid cell which is determined by the selected Cell Layout of the Grid component. The Collider shape can either be the custom physics shape set for the Sprite or an approximation generated from the outline of the Sprite. ![]() Thanks to everyone taking his/her time to read my thread, even if you don't have an answer at hand.Īttached to this post is a screenshot of a bridge prototype, which hopefully makes it better for you to understand. Around 2013, Unity started to support 2D game development with inbuilt components, like a 2D physics engine Collider2D, Rigidbody2D, Vector2, Sprite, Tilemap, etc. Generates a Collider shape based on the Sprite assigned to the Tile. My idea is, to make a Tilemap called "Barrier" with different types of barrier tiles, that I draw around the neccessary parts of the map and shape my own walls.ĭo you think this is a good idea, or should I stick to the Tilemap Collider delivered by Unity? 0.0001), and into an adjacent tiles content. The tearing comes from oversampling a tile by a tiny bit (i.e. no padding between sprites), but this doesnt translate well to a 3D engine since it works by sampling textures coordinates (0-1), not pixels. When the sprite fills a whole grid (1616 in my game) it looks good. Spritesheets are traditionally densely packed (i.e. My problem is that, by using the Tilemap Collider 2D which either creates a collider corresponding to the sprite or to the grid, parts of the terrain are very tight and feel unatural, when walking into or past them. The Unity documentation refers to the following collider types: Static colliders: The GameObject has a collider but no physics body (Rigidbody or ArticulationBody). Hey friends, I found the collider (Tilemap Collider 2d with Composite Collider 2D) doesnt fit some sprites shap well. ![]() I'm making a top down RPG game, which contains various types of colliders such as bridges, wells, houses - you get the idea. I have so many ideas and already found a great source that provides me with enough art, since I'm more interested in the coding part. In 3D, these are the Box Collider, Sphere Collider and Capsule. The simplest (and least processor-intensive) colliders and the so-called primitive collider types. In the example below, the imported Sprite is a 256x128 image, and the Isometric Tilemap has a Cell Size of (XYZ: 1, 0.5, 1) Unity units. A Collider’s type defines how it interacts with other colliders, and how it responds to simulated physics forces. A collider, which is invisible, need not be the exact same shape as the object’s mesh and in fact, a rough approximation is often more efficient and indistinguishable in gameplay. Then, once you have the right shape, reset your Tilemap Collider and youre good to go. To edit the Tilemap Collider, go to the Sprite Editor in the Sprite youre trying to use and modify how you want it to by clicking in Custom Physics Shape. Unfortunately the grid is not precise enough this way and after going only a few tiles from the center, it no longer aligns close enough to fit into the spaces near the walls things can’t pass through single spaced openings etc.ĭropping it down to Diameter 0.I just started making 2D games today. To make the generated Physics Shape match the cell of the Tilemap instead, select the Tile Asset and set its Collider Type property to Grid. In your case you have square tiles and the Tilemap Collider box fits it naturaly. Both the Box Collider A cube-shaped collider component that handles collisions for GameObjects like dice and ice cubes. Obstacle Layer: Walls(my Hex grid has a tilemap collider on it with a layer wall) Composing with the Box Collider 2D and Polygon Collider 2D. Also has customisable options like alpha tolerance and detecting islands and simplifying the collider to use less vertices. ![]() Node Size: 1.23(Best I could get to match the unit width) You pretty much can just drop the AdvancedPolygonCollider.cs script onto the game object that has the sprite and it will generate a PolygonCollider2D based on the outlines of the sprite. Does anyone have any idea on how to match the Unity hexagon grid from the new 2D tools? I’ve been trying for 2 hours to get them to work properly but the node sizes are not the same and I can’t quite get them to match.įor Clarification my game is not a grid based 2D game but uses tilemap to make the levels.Ĭell Size: (1, 1.154701, 0) (By Default they are squished to fit 1x1 unit, this makes them approximately regular hexagons)
