Trigger Blocks
Trigger Blocks adds a set of Forge map-making blocks that react when a player or entity passes through them, and it adds a creative tab for them.
What it does
A trigger block watches its area, and when an entity enters it, a power signal is sent to a receiver placed up to five blocks away. Builders can use this to open doors, start effects or move parts of a map without commands. A killbox works in a similar way, removing any entity that enters it. An inspection plate sends a signal when a player clicks it, to a receiver five blocks away in a chosen direction, and a checkpoint marks where a player returns after a fall or death.
The blocks are meant for creative map making and adventure maps. Trigger Blocks adds its own creative mode tab so the blocks can be found without searching. It runs on Forge for Minecraft 1.20.1 only, and both the server and every player need it. The code is not open source; the mod is released under All rights reserved.

How it compares
Checkpoints is a client-side only Forge mod under the MIT License, with files for 1.20.1 – 1.21, so it does not need to be on the server. Creative Tab Item Obliverator is also client-side only and open source under the MIT License, but it is for 1.20.1 alone and changes the creative tab rather than adding map blocks. Block of Power is a client and server mod for 1.20.1 with All rights reserved, so it is not open source.
