How it works
The serialized ports identify two inputs, IN_A and IN_B, and one OUT.
Named ports
These labels come from the serialized build definition. Verify orientation after placing the machine in-game.
Which ports belong to a merger?
The serialized build definition names IN_A and IN_B as inputs and OUT as the output. Use those labels to distinguish it from the splitter, which has one input and two outputs. Confirm the orientation after placing the item rather than assuming a screen direction.
The developer’s patch 1.0.4 notes describe alternating between merger inputs. That dated statement should not be used as proof of an untested timing or throughput rate for every game build.
Check both sources and the receiver
The merger is the two-input, one-output junction in the extracted port list. If only one side supplies material, inspect that source and its connection before changing the other branch. If both sides stop at the junction, also inspect the single downstream output and destination.
The developer’s 1.0.4 notes describe alternating inputs, but no sustained throughput or fairness measurement has been verified in our analyzed build.
If it isn’t working
- Check that each belt faces the intended port and the output is not blocked.
Frequently asked questions
Does a merger combine two belts?
Its build definition identifies two inputs and one output. Check the connected paths and version-specific behavior in-game.
How much does a merger cost?
The analyzed structure definition lists a $5 base price. Check the build menu in your current game version.
Is the merger the same as a splitter?
No. Its extracted ports are two inputs and one output; the splitter has one input and two outputs.
Base price, ports and numeric specifications are from static game files for build f87fd7e5. Performance and actual placement have not been verified in-game. Game updates can change these values. Read the methodology. For the dated behavior changes, see the developer’s 1.0.4 notes.
