# Tag To This function block lets you publish a value under a short text tag so other blocks in the same scene can retrieve it. Use it together with the `Tag From` block to pass data around without direct connections. ## đŸ“Ĩ Inputs This function block has no input sockets. ## 📤 Outputs `Generic` Provides the value published by the matching `Tag From` block. ## 🕹ī¸ Controls `Tag` Enter a short text label used to identify the value you want to publish. The same text must be used on the matching `Tag From` block to receive this value. (hint: keep the tag concise and avoid leading/trailing spaces) ## 🎨 Features * Lightweight in-scene referencing for sharing data between distant parts of a design. * Works without drawing a cable: matching is done based on the `Tag` text. * Ideal for passing configuration values, flags, or intermediate results when a direct connection is inconvenient. ## ⚙ī¸ Running mechanism When the scenario runs, this block looks for a `Tag From` block in the same scene whose `Tag` text exactly matches the one entered here. If a match is found, the published value from that block is returned on the `Generic` output. If no match is found the block reports an error and is marked invalid. ## 📝 Usage instructions 1. Place a `Tag From` block somewhere in your scene and set its `Tag` to a chosen label. 2. In this block set the same `Tag` label. 3. Connect the output of this block to any consumer that accepts generic data, or use it to bridge distant parts of the flow. ## 💡 Tips and Tricks * Always pair this block with the `Tag From` block — they form a simple publish/subscribe pair. * Use short unique tags to avoid accidental collisions. Tags are matched exactly, so watch for extra spaces. * Combine with `Show Image` or `Image Logger` when you need to forward an image preview or save images originating from a different part of the flow. * For data that must be shared across scenes or stored for later, consider combining with `Data Write Global` and `Data Read Global` as an alternative approach. * Use alongside `CSV Export` to send logged values to a file; the `Generic` output can carry structured data prepared elsewhere. ## 🛠ī¸ Troubleshooting * If you see an error about a missing match: check that a `Tag From` block exists in the same scene and that its `Tag` text matches exactly (no extra spaces). * If the output is empty or unexpected: verify that the publishing `Tag From` block is active and producing a value before this block runs. * To prevent confusion, keep a short naming convention for tags (for example, use lowercase with underscores). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
