isometric tilemap rendering added

PR #2 I'm close to fulfilling all the requirements

[ggondim]

Hi @pankaj-bind, when you think you're done, please mention me at this PR. I'm considering joining forces to make it happen in issue #1.

[SaurabhCodesAI]

Hi @ggondim and @pankaj-bind!

I reviewed PR #3 in detail. @pankaj-bind has built a really solid foundation here, the architecture is clean, the chunk system works well, and the documentation is Great work!

I found some bugs that need fixing before merge:

Critical Issues:

1. Camera rotation (Q/E keys) - input actions defined but not wired up
2. Highlight cursor positioning - appears in wrong location due to transform bug
3. Only 3 pitch levels implemented instead of 4 (missing TOP_DOWN at 90°)

Missing Features:
4. Block placement/removal has no controller support (only mouse)
5. Block animation system exists but renderer doesn't use it
6. Chunk auto loading defined but not implemented
7. Undo/redo doesn't preserve block height

Code Quality:
8. Several unused functions (_create_colored_texture, trigger_block_walk_over)
9. chunk_load_distance variable defined but never used

I'd love to collaborate with @pankaj-bind to fix these and complete the implementation. I can:

• Fix all the critical bugs
• Add missing TOP_DOWN pitch
• Complete controller support
• Implement chunk auto loading
• Add comprehensive testing

@pankaj-bind would you prefer I fork your branch and submit fixes as a PR to you, or should we coordinate on fixing these together?

@ggondim given the additional scope, how would you like to structure the bounty? The MVP is 70% there, but these fixes will take another 8-10 hours to do properly.

[pankaj-bind]

@SaurabhCodesAI let's coordinate on fixing these together

[ggondim]

@SaurabhCodesAI, that's an excellent outcome from the review. I can't precisely gauge the workload required for this, but I'm considering duplicating the bounty so that each of you receives the same amount. If you prefer, you can also suggest a new one following the README instructions. Just let me know. Additionally, I'm working on a new backlog/roadmap with more features.

[SaurabhCodesAI]

Hey @ggondim!

Works for me, duplicating the bounty is fair. Let's do it.

@pankaj-bind, here's the split:

You handle:

• Animation system hookup - your get_current_frame() just needs calling from _render_block()
• Code cleanup - unused functions if any

I'll take:

• Q/E rotation wiring DONE
• Camera transform bug fix DONE - Fixed screen_to_world() to apply reverse heading rotation
• 4th pitch level (90° top down) DONE - All 4 levels verifying and documenting
• Controller support for place/remove DONE - A/B buttons mapped (Home/End on keyboard)
• Chunk auto loading implementation DONE - Dynamic loading within 3 chunk radius
• Undo/redo height fix DONE - Added height preservation to action dictionary

You're building on your stuff, I'm handling the system integration. Sound good?

Let me know if you want PRs to your branch or we work in parallel.

@ggondim, my tasks are complete and tested in Godot 4.5.1. Demo video and final polish will come in the next phase to ensure we hit 100% of the README requirements. Happy to discuss the full scope, also curious about the roadmap you mentioned!

[SaurabhCodesAI]

Hey @pankaj-bind updated the task split above with your remaining items (animation hookup, code cleanup). Let's wrap this up!
Also, My tasks are done. Can you add me as a collaborator to your fork so I can push the changes to issue-1? Thanks!

[pankaj-bind]

@SaurabhCodesAI You did an excellent job.
Thanks.
Soon, I'll finish code cleanup, and it's done.

[SaurabhCodesAI]

Thanks @pankaj-bind! Great working with you. Let me know if you need any help with the cleanup.

[pankaj-bind]

Hey @ggondim, everything looks good to me. @SaurabhCodesAI has done an excellent job. I believe this PR is now ready to be merged.
