Thank you Cairyn and Ferdinand again. This is all making much more sense now, I appreciate you helping me understand how to correctly set up a simple interface. I do need to spend more time just learning the fundamentals of Python.

One more question on this topic. I have tried to combine Cairyn's note on creating a button with the py-commanddata_dialogr13 script from Maxon github to create an async dialog.

For some reason, it will not add my button to the dialog-basically just trying to add buttons to the py-commanddata script. Do you have any possible suggestions on making something like this work? Basically would like an async dialog with buttons. Thank you for any advice.

Thank you Cairyn and Ferdinand, this is all very helpful and I have a better understanding of different ways to approach this type of project.

Yes, I do not think I want to run an external script, just have one script that a user can perform a few different commands from. Essentially so they can just have one command icon ( script ) in their interface and when they click on that it opens up a GeDialog with a bunch of options they can run by clicking on buttons inside of the GeDialog vs having to click on a bunch of different scripts. I assume those buttons are essentially other scripts that are all bundled together that they would drop in their scripts folder.

I am so excited about all of the possibilities of adding programming into my daily work as a c4d animator-it is challenging to learn from a non-programming background but this forum has helped a lot.

Thanks again.

stereo_stan

Thank you. Yes, the goal is to be able to execute multiple commands in one plugin so I was trying to find a way to connect the GeDialog with some commands.

I am new to programming and I have read through the GeDialog documentation and I can not figure out a way to connect the two concepts.

Is there some example code that creates a few buttons that run some commands?

Thank you for your help, I appreciate it.

Hi everyone, I am trying to learn how to code python by modifying the maxon scripts.

I have this basic script working as a plugin. It makes the object editable and moves the anchor point. I am trying to figure out a way to make this work with a button click instead of just clicking on the script to run it.

Can you please help me get one or two buttons to work with this code? Thank you for any guidance!

Thank you Ferdinand, sorry for not posting correctly-I will work on making sure to understand the correct way to interact on the forum as I move forward.

Hi everyone. I am trying to learn Python and I have been trying to modify scripts from the official C4D Github page.

I want to see how I could possibly add a GUI button to this code that copies an animation curve from one object to another.

I have tried combining two different scripts here.

I am trying to get when the user clicks the ok button it copies the curve and adds to the other object. Right now the script will do that but only when you click execute.

Please let me know if you have any thoughts, thank you!
