MEPLua Scripting

MEPLua scripting runtime with custom 3D game development API

📜 Script Lifecycle

Two main callbacks: on_start() runs once at Play, on_update(dt) runs every frame with delta time.

🏗️ Instance System

Create objects at runtime with Instance.new("Part"). Full hierarchy with FindFirstChild() and GetChildren().

Connect to events: part.Touched:Connect(func), humanoid.Died:Connect(), HealthChanged.

🎭 Humanoid Control

Character properties: Health, MaxHealth, WalkSpeed, JumpPower. Full character rigging with Motor6D.

⏱️ Timing Functions

Built-in helpers: wait(), delay(), spawn(), tick() for async operations.

-- Example: Spinning Color-Changing Part
local part = script.Parent
local rotation = 0

function on_start()
    print("Part initialized: " .. part.Name)
end

function on_update(dt)
    rotation = rotation + (90 * dt)
    part.Rotation = Vector3.new(0, rotation, 0)
    part.Color = Color3.fromHSV(rotation / 360, 1, 1)
end

Frequently Asked Questions

Answers to common questions about MEP

No! MEP is 100% portable. Just extract the .rar file and run MicahEngineStudio.exe. No Python, no dependencies, no admin rights needed. Works on USB drives and cloud storage too.

MEPLua is a custom scripting language built specifically for game development. It includes Lua-like syntax but adds MEP-specific libraries: Instance.new(), Vector3, Color3, CFrame, and event systems. It's not standard Lua.

Currently, MEP is a sandbox/creation tool. Games run within the editor. Future versions will include build-to-EXE for standalone distribution. For now, share your .mep project files or record gameplay videos.

OS: Windows 10/11 (64-bit). RAM: 4GB minimum (8GB recommended). GPU: OpenGL 3.3 compatible (Intel HD 4000+, AMD HD 7000+, NVIDIA 400+ series). Storage: 500MB free space.

MEP can handle 1000+ objects in a single project. Performance depends on your GPU and complexity. Modern GPUs can render thousands of objects at 60 FPS. Benchmark your setup in the editor.

Post in the #bug-reports channel on Discord with screenshots, error messages, and steps to reproduce. Or open an issue on GitHub. All bugs get fixed in the next update.

Project files: .mep (proprietary format). 3D models: OBJ with MTL materials. Textures: PNG, JPG. Audio: WAV, MP3. PNG and JPG recommended for performance.

Yes! Source code is available on GitHub under MIT License. You can contribute, fork, or use code in your own projects. Community contributions welcome!

Yes! MEP is free for personal and commercial use. You can sell games made with MEP, modify the source code, and use it in any project. MIT License has no restrictions.
