Am I using 'ontimer' incorrectly?

In the future, please create a new post for your questions.

The vizact.ontimer command is expecting a function object as the second argument. Instead, you are giving it the result of calling the suivi function. You should just pass the function instead of calling it:

# Call 'suivi' every frame with 'init' argument
vizact.ontimer(0, suivi, init)

Thank you for your answer and sorry to up an ancient post.

I will ask an other question in a new post.
