I apologize, but the query does not contain a specific question. The user has only provided some image links without any accompanying text or query. Could you please clarify what specific information or assistance you are seeking about these images or the Vampire Survivors tutorial series?

To help you effectively, I would need:

1. A specific programming question
2. Context about what you’re trying to accomplish
3. Details about any particular issue you’re experiencing

Would you like to rephrase your query or provide more specific details?

I had a problem generating the map, I did everything as in the video, but nothing works. It just creates new objects all the time and doesn’t display them.

Based on the reference information, here are some potential solutions:

1. Check your chunk generation code, specifically the SpawnChunk() and ChunkOptimzer() methods. Ensure they are correctly implemented.

2. Verify that your terrain chunks are properly set up:

• Create an empty GameObject named “Terrain Chunk”
• Reset its Transform
• Drag Background Grid as a child
• Create a “Props” child GameObject
• Create prop location points within the tilemap bounds

3. Troubleshoot common tilemap issues:

• Check for gaps between tiles (ensure uniform tile sizing)
• Disable Anti-Aliasing in Project Settings > Quality
• Verify tile settings are consistent

Could you provide more specific details about:

• Your current chunk generation script
• How you’ve set up your terrain chunks
• Any specific error messages you’re seeing?

Can you post your MapController script here as well?

Based on the code provided, here are potential issues causing map generation problems:

1. currentChunk is not set: The script returns immediately if currentChunk is null, preventing chunk generation.

2. Ensure you have:

• Assigned player in the Inspector
• Populated terrainChunks list with chunk prefabs
• Set currentChunk to the initial starting chunk
• Configured checkerRadius and maxOpDist

3. Verify PlayerMovement script is correctly setting moveDir

Could you confirm:

• Have you set up all required references in the Unity Inspector?
• Is your PlayerMovement script correctly updating moveDir?
• Do your terrain chunks have child objects named “Right”, “Left”, “Up”, etc.?

Can you add the highlighted portions to your ChunkChecker() function, as shown below:

void ChunkChecker()
{
    if (!currentChunk)
    {
        return;
    }

    if (pm.moveDir.x > 0 && pm.moveDir.y == 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Right").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk on the right");
            noTerrainPosition = currentChunk.transform.Find("Right").position;  //Right
            SpawnChunk();
        }
    }
    else if (pm.moveDir.x < 0 && pm.moveDir.y == 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Left").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk on the left");
            noTerrainPosition = currentChunk.transform.Find("Left").position;    //Left
            SpawnChunk();
        }
    }
    else if (pm.moveDir.y > 0 && pm.moveDir.x == 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Up").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk upwards");
            noTerrainPosition = currentChunk.transform.Find("Up").position; //Up
            SpawnChunk();
        }
    }
    else if (pm.moveDir.y < 0 && pm.moveDir.x == 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Down").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk downwards");
            noTerrainPosition = currentChunk.transform.Find("Down").position;    //Down
            SpawnChunk();
        }
    }
    else if (pm.moveDir.x > 0 && pm.moveDir.y > 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Right Up").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk on the right up");
            noTerrainPosition = currentChunk.transform.Find("Right Up").position;   //Right up
            SpawnChunk();
        }
    }
    else if (pm.moveDir.x > 0 && pm.moveDir.y < 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Right Down").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk on the right down");
            noTerrainPosition = currentChunk.transform.Find("Right Down").position;  //Right down
            SpawnChunk();
        }
    }
    else if (pm.moveDir.x < 0 && pm.moveDir.y > 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Left Up").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk on the left up");
            noTerrainPosition = currentChunk.transform.Find("Left Up").position;  //Left up
            SpawnChunk();
        }
    }
    else if (pm.moveDir.x < 0 && pm.moveDir.y < 0)
    {
        if (!Physics2D.OverlapCircle(currentChunk.transform.Find("Left Down").position, checkerRadius, terrainMask))
        {
            print("Spawning chunk on the left down");
            noTerrainPosition = currentChunk.transform.Find("Left Down").position; //Left down
            SpawnChunk();
        }
    }
}

Then let me know the messages that show up when your game is running.

I suspect either your chunks are set up improperly, or the chunk checker GameObjects are set up such that they keep firing incorrectly.
