Can you make a new (paid) C# course about a full / "advanced" RPG combat system with abilities, status effect etc. This may sound selfish but I think RPGs are a popular genre, so it would be useful for others too, what do you think? You said you want to make a grid based tutorial, maybe you can combine it and make the RPG combat system of the course turn/grid based.

[@arcday4281]

The system is complex and depends on the specific requirements for it ! I think it's better for you to create it yourself - since such an "asset" will be confusing - and you will still need to understand it in order to change, add or fix something ! It is quite possible to do this based on the video content of "Code Monkey"! And yes, I am a fan of such games (especially "old school") I hope you will be able to create a full-fledged RPG and we will play it with pleasure )))

[@Hietakissa]

@@arcday4281 It's easier to learn (and understand) something when a genuine professional makes it while simultaneously talking about it. Yes, they need to understand it in order to modify it and to use it properly, and they will if someone teaches them how it works.

Yup making another C# course is definitely something I'd love to do, now that I've been working more and more with 3D it would be great to do a 3D Survival RPG or making a Factorio-like. The main issue as usual is time, so I'd love to do it but not sure when.

[@BlackJar72]

Being able to do this is exactly what I need to do -- except it really doesn't. It would be so much more useful to be able to do this in code to create a system for player created content (think of players adding doors and windows to Sims houses).

[@CodeMonkeyUnity]

ProBuilder is open source so you can just go through the package code to find out how to call that from your own code. Although making a player mechanic using this would probably not be recommended, remember this is still marked as experimental so I would make a core mechanic in your game based on an experimental feature.

Please don't give such videos name and preview image that don't describe its content I was expecting to learn in more details the way to substitute original objects with its shattered version And even if it's "part one", you'd expect it to be stated in the beginning of the video, the title or preview

@@CodeMonkeyUnity So in my own projects essentially what I was doing is: Make an object, save a reference to a shattered object in a script attached to whole object, and when it breaks I just instantiate a shattered version and destroy a whole one. Judging by the title, preview (both the image and a little gif playing when hovering over a video) and demonstration at the beginning I was expecting to see the whole process of how you achieved that effect (to see if my way is less optimal or professional), but I've only seen how to cut meshes with probuilder and been told at the very end "the rest will be in pt.2" That's what I was upset about

It sounds like you're having trouble simply thinking about how to connect all the pieces to build the mechanic you want but everything is shown on the video. You use the Intersect action to slice the object in 2 parts. Then in the code when the player slices the object you destroy the unsliced object and spawn the two slices and give them an explosion force.
