Uppercase Text in TouchDesigner

In touch designer is there a way to force my text to appear uppercase?

ChatGPT

Yes, in TouchDesigner, you can force your text to appear uppercase using Python scripting. Here’s how you can do it:

1. Using a Text TOP:

   • Place a Text TOP in your network.
   • In the Text parameter, you can use a Python expression to convert the text to uppercase.
   • Click on the little python icon next to the Text field to switch it to an expression.
   • Enter a Python expression like this:

     "your text here".upper()

2. Using a Text DAT:

   • Place a Text DAT in your network.
   • In the Text DAT, you can use a Python script to set the text content to uppercase.
   • Write a script like this:

     op('text1').text = "your text here".upper()

     Replace text1 with the name of your Text DAT.

3. Using a Script to Modify Existing Text:

   • If you have text coming from another operator and you want to convert it to uppercase before displaying it, you can use a Python script to modify the text.
   • For example, if you have a text parameter in another operator, you can write a script to update it:

     op('your_operator').par.Text0 = op('your_operator').par.Text0.eval().upper()

By using these methods, you can ensure that the text in your TouchDesigner project is displayed in uppercase.

I tried this please correct it:

op(‘combined_text’).par.text.upper()

ChatGPT

Your attempt is close, but there’s a small adjustment needed to properly set the text to uppercase. You need to use the .eval() method to get the current value of the parameter, convert it to uppercase, and then assign it back to the parameter.

Here is the corrected version:

op('combined_text').par.text = op('combined_text').par.text.eval().upper()

This script retrieves the current text from the combined_text operator, converts it to uppercase, and then sets the parameter back to the modified text.

I was using this to reference a text TOP in a text DAT: op(‘static_text’).par.text

But I’ve now collapsed the DAT to a level below, how can I reference the TOP now that it’s a parent container?

ChatGPT

If you’ve collapsed the DAT into a parent container, you’ll need to use a relative or absolute path to reference the Text TOP from the parent container. Here’s how you can do it:

1. Relative Path:

   • If your Text TOP is within the same network level as the Text DAT, you can use a relative path. For example, if your Text TOP is in a parent container called parentContainer, and the Text DAT is within parentContainer, the relative path would look like this:

     op('parentContainer/static_text').par.text = op('parentContainer/static_text').par.text.eval().upper()

2. Using parent() to Traverse Up the Hierarchy:

   • If your Text DAT is nested within a container and you need to move up the hierarchy to reference the Text TOP, you can use the parent() method. Here’s an example assuming the Text DAT is one level below the Text TOP:

     parent().op('static_text').par.text = parent().op('static_text').par.text.eval().upper()

3. Absolute Path:

   • If you prefer to use an absolute path (starting from the root of the TouchDesigner network), you can reference it like this:

     op('/path/to/parentContainer/static_text').par.text = op('/path/to/parentContainer/static_text').par.text.eval().upper()

Here is a more specific example assuming the following hierarchy:

/project1
  /parentContainer
    /text_DAT
    /static_text (Text TOP)

From text_DAT, you can reference static_text using:

parent().op('static_text').par.text = parent().op('static_text').par.text.eval().upper()

Make sure to adjust the paths according to your specific network structure.
