Project EMapper

Project EMapper is an in-game helper for ProjectE that makes it easy to find items that are missing EMC (or already have EMC), set custom EMC values via a simple UI, save them directly into ProjectE’s custom_emc.json, and then reload datapacks so ProjectE picks up the changes—without needing to type commands.

Set or change an EMC value

1. Click an item in the list

2. Type a number into EMC value

3. Click Apply (local) to stage the value

Staging lets you set a bunch of values first, then save once.

Reload ProjectE values

• Click Reload ProjectE
• This triggers an internal /reload, which makes ProjectE rebuild its mapping with your new values.

Troubleshooting

“My EMC changes didn’t apply.”

• Make sure you clicked Save to custom_emc.json
• Then click Reload ProjectE
• Confirm the item exists in config/ProjectE/custom_emc.json

“I see items like air/bedrock in the list.”

• Some registries include special or non-survival items. You can ignore them, or filter them out in a future update.

Planned Improvements

• Search bar + sorting
• Show current EMC and custom override side-by-side
• Optional “hide non-survival / technical items”
• Server/OP mode with permission checks
