Stick prefabs on a spline, equal distance apart (and also random distance)

[newguy123]

Hi Guys

 

I saw a video a while back, where there was a farm field, and objects was being dropped on the terrain in the farm field on a spline, to form rows of planted stuff. Can't remember where I saw the video.

 

Anyway.... Can I do that with Gena Pro? Take my tree prefab(s) and drop them on a spline, equal distance apart? And on a different spline, random distance apart?

@newguy123 yes, this can be done - Gena Pro has a spline system that allows you to run a spawner along the spline so you can place objects along it. There are options for a throw distance which would allow for randomization in positioning. You can see this in action here around 18:00 where we add rocks to a riverbed:

Note that you can also texture or spawn trees / grass along the spline, and build complete road and river meshes.

How can I spawn the extension using code at runtime? I already tried using the Execute method but it doesn't work

Hi there @gogo,

There actually is a demo of how to use the Spline in the Asset Samples/Script Examples folder. If you look at the GeNaRuntimeExample.cs script, you can see a function called "SplineSpawn" that actually performs a spawn at runtime. 

The reason why 'Execute' doesn't work is because Execute is a method that simply 'Updates' the Spline and all of it's Extensions. This function isn't really intended for public use. Instead, the concept is to get a reference to the Spawner Extension on the Spline (using the example above) and calling methods on it at runtime. 🙂

Hope this helps!
