Procedural race track environment (UNREAL)
polycounter lvl 2
I am working on something a bit similar to roadrash but with the car and endless like subway surfer or other similar 2d race game. Now I have completed car mechanics the way I want it in the game. Now, I am clueless about how can I make the buildings spawn (have created 14 variations of the building as of now) next to the track.
Note- I am keeping the car move forward as in-place mechanics was not really coming along as I wanted.
Please let me know if there's a way to spawn random buildings that will be selected from the set of assets.
Thank you

you can set a variable of any type to be an array on a blueprint.
Do that with static meshes, add all your buildings to the array and select a random index from it to spawn a new static mesh component
I have 1-2 more doubts, 2 buildings have different width so as to avoid any clipping should I omit those or how I can imagine doing this after reading your reply is to create two different arrays, one with buildings of the same width and the other with a different width than rest. Now, I am not sure how to spawn these randomly without spawning two at the same location. Also, I was thinking of putting some roads at random locations so the world won't feel monotonous but I will try to keep the width of the road similar to that of majority of buildings.
Please let me know how I can achieve these smartly.
I really appreciate this gesture of helping, thank you so much. You are awesome.
The algorithm you want depends how irregular you want the layout to be.
For something irregular look at circle packing or Poisson distribution algorithms. For more regular (grid based) layouts the logic is a lot simpler and Ive never bothered to look up an algorithm
As far as working out building sizes goes you can get the bounding box size for a static mesh in your blueprint
Practically speaking though, you'll probably get away with just laying them out on a grid, buildings usually have regular road sized gaps between them anyway
