Two Separate "entity" strings

I'm trying to make a plugin where "OnUserInput" would spawn an entity at a players feet. Ideally, I'd like it to be one or the other. Is it possible to have two (or more) separate strings that can do this? Or am I missing a simple line?

At the moment my line shows;

Code:

        string treeEnt = "assets/bundled/prefabs/autospawn/resource/v2_temp_beachforest_small/douglas_fir_d.prefab";
        string treeEnt2 = "assets/bundled/prefabs/autospawn/resource/v2_arctic_forest/douglas_fir_a_snow.prefab";

Code:

BaseEntity baseEntity = GameManager.server.CreateEntity(treeEnt, player.transform.position + (player.modelState.ducked ? Vector3.up * -0.0f : Vector3.up * -0.0f) + player.eyes.HeadForward());

This just returns errors.

I'm still quite new to C# so slowly getting there, and any advice would be greatly appreciated!

 

Code:

Operator `||' cannot be applied to operands of type `string' and `string'

Probably on the complete wrong area of what I need! Haha.

 

How would I randomize?

 

Thanks mate!
