<h3 id="wrong-uvs">Set correct uvs on terrain mesh</h3>
|
|
|
|
<p>Terrain is using a single texture:</p>
|
|
<p><img src="https://github.com/tetreum/brickcraft/raw/main/Assets/Resources/Textures/Terrain.png"></p>
|
|
|
|
<p>But i don't now how to set the uvs in order to use it properly.<br>
|
|
If i set all vertices, the entire texture is used, which is not what i'm looking for:
|

|
|
<p>With my latest attempt it looks like</p>
|
|

|
|
<p>Each face has only 1 color => good. But it's not the same color across all faces and also it's always the wrong color => fail.</p>
|
|
|
|
<p>Here is the code that handles uvs setup: <a href="https://github.com/tetreum/brickcraft/blob/main/Assets/Scripts/World/ChunkRenderer.cs#L546" target="_blank" rel="nofollow">ChunkRenderer.cs#L546</a>

<h3 id="broken-terrain-mesh">Terrain mesh is randomly broken because of brick's top face</h3>
|
|
|
|
<p>
|
|
In order to generate the terrain mesh, i grab the brick model and i use planes to delimitate each face.
|
|
</p>
|
|
<img src="https://i.imgur.com/XuwjStb.png">
|
|
<p>Notice the blue planes "cutting" each face.</p>
|
|
<p>Then i use a <a href="https://github.com/tetreum/brickcraft/blob/main/Assets/Scripts/Utils/FaceMapper.cs" target="_blank" rel="nofollow">small class</a> that iterates over all brick mesh's vertices to know to which face do they belong.</p>
|
|
<p>
|
|
After that, when building a mesh slice, i just add the visible brick faces of each case at
|
|
<a href="https://github.com/tetreum/brickcraft/blob/main/Assets/Scripts/World/ChunkRenderer.cs#L495" target="_blank" rel="nofollow">ChunkRenderer.cs#L495</a>
|
|
</p>
|
|
|
|
<p>If top face is properly cut:</p>
|
|
<img src="https://i.imgur.com/XuwjStb.png">
|
|
|
|
<p>Then it randomly breaks:</p>
|
|

|
|
|
|
<p>If only studs are set as top face:</p>
|
|
<img src="https://i.imgur.com/s0gMxMJ.png">
|
|
|
|
<p>It doesn't break:</p>
|
|
<img src="https://i.imgur.com/NGUxIuA.png">
|
|
|
|
<p>
|
|
Notice how all other faces are also rendering properly now. Yet they haven't been edited.
|
|
</p>
|
|
<p></p>
|
|
How the heck can they "randomly" break?<br>
|
|
If vertices that are used both in top and lateral faces are the problem, why do they not always break?<br>
|
|
What am i missing out?......<br>

<p>Well, basic feature not made yet.</p>

Digging takes places at <a href="https://github.com/tetreum/brickcraft/blob/34bb70f1a5f7438acf396b9c10a50b8dae50c8a2/Assets/Scripts/Player/Player.cs#L53">/Scripts/Player/Player.cs#L53</a>.

|
|
And <a href="https://github.com/tetreum/brickcraft/blob/main/Assets/Scripts/World/WorldBehaviour.cs#L259">/Scripts/World/WorldBehaviour.cs#L259</a> has some methods to transform coords to Chunks.
