📝 License Summary: This license permits free distribution of the original software version but prohibits distribution of any modified versions. All non-code resources are the private property of the author.

⚠️ Important Notes

1. Legal Validity: Consult a lawyer to ensure enforceability of the terms

2. Conflicting Clauses: The requirement "modified versions cannot be distributed" conflicts with common modpack ecosystems (which often require minor adjustments for compatibility)

3. Alternative Proposal: For broader adoption, consider the following more permissive option:

            // More permissive option (balancing dissemination and protection):
            - Code under MIT License (permits free modification/distribution with attribution)
            - Non-code resources under CC BY-NC-ND 4.0 (prohibits commercial use, modification, requires attribution)
        

📝 Implementation Steps

1. Save the license text as a LICENSE.txt file

2. Clearly mark in the software:

        // Add to the header of code files
        /*
        * Copyright (c) 2024 Zhang Haotian
        * This software's code is governed by the SIRIUS Software License v1.0
        * Resource assets (textures/sound effects, etc.) are private property of the author and prohibited from reuse without authorization
        */
    

3. Declare resource protection clauses in prominent positions on the release page

💡 Practical Impact Examples

✅ Allowed: Users distributing the software
❌ Prohibited: Releasing "modified versions" after moding
❌ Prohibited: Extracting images/sound effects from the software for use in other programs
