Direct answer: In Roblox BedWars Creative mode you get blocks from the Creative menu (inside your inventory) or by using the creative commands; in regular competitive matches blocks come from the Item Shop or from kit- specific items — glitches like “ghost blocks” are community-found exploits and are unstable and often patched.

How to get blocks — short steps

  • Creative worlds: open your inventory and click the "..." or Creative menu to browse and spawn any block type available in Creative mode.
  • Custom/creative commands: server owners or map makers can use Creative commands to give themselves infinite blocks or spawn blocks directly (these are accessible in Creative or by authorized commands).
  • Normal BedWars matches: buy blocks from the Item Shop during a match (wool, wood, etc.), or use kit-specific abilities that supply building materials.
  • Ghost/infinite-block glitches: players have shared methods (timing key presses, inventory tricks, or exploit-like actions) that create “ghost blocks,” but these are unreliable, can be patched, and may trigger anti-cheat or account penalties. Use at your own risk.

Quick tips for Creative building

  • Use the inventory Creative menu to quickly select full stacks of different block types for building.
  • If you’re making a custom map, learn the Creative commands list so you can spawn, copy, and delete blocks faster.
  • Save versions of your map frequently in case a glitch corrupts the world or the game updates.

Example (simple workflow)

  1. Join or create a BedWars Creative world.
  1. Open inventory → click the "..." to open Creative menu.
  1. Select block types, place freely, or use creative commands to spawn large quantities.

Safety and fairness note

  • Stick to official Creative mode and legitimate Item Shop purchases for stable gameplay; exploiting glitches can be unfair to others and may get fixed or punished by the developers.

If you want, I can:

  • Give step-by-step instructions tailored to the current BedWars UI you see (tell me what buttons/options you see).
  • Summarize the most common creative commands and where to find the official help/docs.
