Hi, I’m creating a 2d top to bottom tower game (Line tower wars)
I’m completely lost on how I should go about implementing my map with a grid.
How would I take vertices from a mesh and use them to place my tiles, and also use them for tower placement and pathing etc? I am working in c# , very new to coding, and game dev.
Is there a way to generate a quad mesh?
How do I store my grid points?
Do I use an array, index, dictionary, nodes, or something else?
Please help! Thanks!
My text map (0= playable area (grass), 1 = border wall, 2 = starting/end zone)
