Multi-Spawner Tool

Update 1.3 - Terrain Snapping & Physics Improvements

Thanks to everyone checking out the tool! Version 1.3 focuses on stability, terrain handling, and requested quality-of-life toggles.

What's New:

• Terrain Height Alignment: Entities now use a downward trace to find the ground. No more NPCs getting stuck halfway into hills, ramps, or uneven terrain!
• Freeze Props Toggle: Added a checkbox to spawn props frozen in place. This prevents props from colliding instantly and launching across the map.
• Face Player Option: Added a setting to make spawned NPCs look directly at you instead of facing your eye direction.
• Optimized Formation Calculation: Prop spacing is now calculated efficiently once per batch instead of repeating every loop iteration.
• Performance Cap: Balanced the spawn limit to 60 to protect frame rates and prevent sudden engine freezes.
• Code Refactor: Cleaned up code structure, unified variable naming, and polished UI controls.

Multi-Spawner Tool (NPCs & Props)

Welcome to the Multi-Spawner Tool! A lightweight, reliable utility designed to eliminate spawnmenu spam by spawning clean formations of NPCs and props with a single click. Fully optimized for Sandbox and multiplayer servers.

Features:

• Squad NPC Spawning: Deploy balanced squads of any NPC in clean, forward-facing rows.
• Batch Prop Formations: Spawn physics props in structured grids aligned to your line of sight.
• Automatic Spacing: Entities are spaced intelligently so they never spawn stuck inside each other.
• Dynamic Loadouts & Presets: Supports both default HL2 weapons and custom addon NPC loadouts, models, and skins.
• Server Friendly: Strictly respects server limits and integrates with Prop Protection addons (FPP, APG, CPPI).
• Adjustable Quantity: Choose anywhere from 1 to 100 entities via a simple slider.
• Full Undo & Cleanup: Press Z to undo the entire batch at once, or remove them via the Sandbox Cleanup menu.

Controls:

• Primary Attack (LMB): Spawn the selected amount of NPCs.
• Secondary Attack (RMB): Spawn the selected amount of Props.
