Random object placement.

Hello at first. I’ve got a question about terrains. I have got 10 terrain templates and ı want to place them randomly. Infinite map that goes on and on. for example;

object is going 100 blocks (I don’t know what term do we use for pixel at 3d universe) and map ends. I want to create a 100 block wide terrain again randomly. I hope i can explain it well. Somebody can help me ? thanks a lot.

If you have an array of objects, you can pick random(0,length of array). This gives you a random tile (?) and then you place them / instantiate them at the given world coordinates (vector3), like if you have a 10 by 10, you can do two loops, so looping 1 to 10, and for each loop 1 to 10, that gives you all 100 positions (or multiply with some number to get the right positions) then use that for the position parameter of the instantiate.
