No, cave spiders cannot fit through trapdoors in Minecraft.
Understanding Cave Spider Dimensions
Cave spiders are notably smaller than most other hostile mobs found in the game. Their compact size makes them unique; they are roughly the same size as a single slab block, which measures out to half a block in height. This slender profile typically allows them to navigate narrow, one-block-high spaces that larger creatures cannot access.
Why Trapdoors Stop Them
Despite their small stature and ability to fit into tight spots, a closed trapdoor acts as an effective barrier against cave spiders. When a trapdoor is placed and closed, it creates a solid obstruction that specifically prevents these agile creatures from moving through the space it occupies. This interaction is key for players looking to control mob movement.
Practical Applications and Block Interactions
The unique interaction between cave spiders and trapdoors has several practical implications for players:
- Mob Control: Trapdoors are a common component in Minecraft mob farms or defensive structures. They are strategically used to funnel, contain, or block cave spiders from escaping designated areas or entering safe zones.
- Hitbox Dynamics: While cave spiders have a small hitbox (0.7 blocks wide and 0.5 blocks tall), a closed trapdoor effectively functions as a full-block barrier in terms of preventing mob passage, confirming that it will "stop them."
- Farm Design: Understanding that trapdoors block cave spiders is crucial for designing efficient cave spider experience (XP) farms, ensuring that the spiders are contained and guided as intended for collection.
Cave Spider vs. Trapdoor Interaction
| Characteristic | Cave Spider | Trapdoor (Closed) | Impact on Passage |
|---|---|---|---|
| Size (Height) | Half a block (0.5 blocks) | Effectively one block (when closed) | Blocks passage |
| Primary Function | Hostile mob | Interactive block, creates a barrier | Prevents movement |
| Mob Interaction | Stopped by closed trapdoor | Acts as a solid wall for mobs | Cannot fit through |
