Question Terrain Deformation during runtime

Hi all!

I'm trying to find out how to make a terrain deformation script which, when the player "activates" the tool and then clicks an area on the terrain, it then increases/decreases that area appropriately.

However, when trying to find material that does something close to this, it turns out is 6+ years old and uses old code that is now deprecated.

I know, I need to be using things like

heightmapResolution()

instead of

heightmapWidth()/heightmapHeight()

for example.

I would be having a look at some of the assets within the unity store to see how they do this, however I don't have much in terms of money to be able to fork out a purchase.

As such, I was wondering if anyone knew of any resources that are using the more up to date code which would step me through how to achieve something like terrain deformation, or, point me in the direction to be able to figure it out?

 

There may very well be simpler solutions or ready made assets for this. But you may be able to use tesselation or something of the nature. when the player clicks on the terrain, trigger a "painting" of the tesselation map in the area corresponding to the terrain.
