how to delete blocks in siren head legacy roblox

Direct answer: In Siren Head Legacy on Roblox you can't delete other players’ placed blocks unless the game's build mode or your account has a delete/undo tool and the developer allowed removal; when building in Studio or in build- mode gameplay, blocks are removed with the in-game delete tool or by a script that destroys parts (for example Destroy() on the part).

Quick steps (in-game build mode)

• Open the build menu and switch to the Delete or Remove tool if the game provides one; use it on the block you want removed (this is how Piggy-style delete tools work in Roblox build modes).

• If you placed the block and there’s an undo or trash icon, use that — many user-made games include an undo stack or inventory delete inside the build GUI.

If you have access to editing in Roblox Studio (developer or local copy)

• Select the block(s) in Explorer or the viewport and press Delete, or right-click → Delete; you can also call part:Destroy() from a server or local script to remove parts programmatically.

• To delete many parts efficiently in a script, loop through a Folder and call :Destroy(), yielding occasionally (for example RunService.Heartbeat:Wait() every N parts) to avoid lag.

If you want a delete-by-collision behavior (scripting approach)

• Use a Touched event to detect collisions and call :Destroy() on the target part, making sure parts are CanTouch = true and your conditions check the hit’s name/parent to avoid false positives.

Troubleshooting

• If the game doesn’t show any delete tool, you likely lack permission — contact the game’s developer or check the game’s description/Discord for build-mode rules. The creator may intentionally block deletion of other players’ builds to prevent griefing.

• If deleting causes lag when many parts are removed, batch the destroys and yield periodically or reuse parts instead of destroying/instancing repeatedly to improve performance.

Example script snippets (conceptual)

• Single part destroy on touch:
  • script.Parent.Touched:Connect(function(hit) if hit.Name == "DeleteBlock1" then script.Parent:Destroy() end end).

• Bulk delete with periodic yield:
  • for i,v in pairs(folder:GetChildren()) do v:Destroy() if i % 100 == 0 then RunService.Heartbeat:Wait() end end.
