Welcome!

I need to add a "seed" for resources.

I explain - for example, I want to plant a tree, I need to create a seed of this tree, then the ability to plant this tree, and accordingly track its growth, make it grow gradually, maybe there is an example of a plugin so that I can familiarize myself with this event, or tell me at least a couple in words
...

Thank you in advance! :)

I created plugin like this. Is done but need some small changes like custom item icons.

Trees growth
Planting Trees
Cuting Trees
