Hi there,

I have a running project, where I was wondering if there is an easy way to animate an timer on a bomb through the fonts node?
Any suggestions?

Many thanks,

Of course. One of the possible ways is to use Python expression inside the Text parameter.

For example:
target_seconds = 5
second = target_seconds + 1 - (hou.frame() / hou.fps())
if second > 0:
    return int(second)
else:
    return 0
It must always return some value.

Thanks for your suggestions! Is there any way to add kind of timecode in the text parameter?

Python's time [docs.python.org] module might be a good starting point. And if you don't want to use it, you can accomplish the task with some math and string concatenation. There are a lot of examples on the Internet covering the creation of countdown timers in Python.
