in this code I build a matrix (tile heights)
then I create all the tiles - I need to connect up all the tiles vertex to create a terrain.
I need to store a vertex displacement list for each tile so when it is spawned, or it’s physics is spawned, I can deform them.
I create a list right now for each tile (neighbor tiles) (PL=[])
I am having trouble understanding how to loop through the data I have and create this ‘vertex displacement list’
then the tiles will be removed,
LOD adds the tiles back + applies the ‘Vertex displacement list’ to the newly added mesh as needed.
The part I need help with, is what to do after
#Get all neighbors for each tile
for object in store:
x = object[4]
y = object[5]
print(x)
print(y)
PL = []
if x>=1:
T1 = own['Matrix'][x-1][y]
PL.append([T1,x-1,y])
if y<=98:
T5 = own['Matrix']
PL.append([T5,x-1,y+1])
if x<=98:
T2 = own['Matrix'][x+1][y]
PL.append([T2,x+1,y])
if y<=1:
T3 = own['Matrix'][x+1][y+1]
PL.append([T3,x+1,y+1])
elif y>=1:
T4 = own['Matrix'][x+1][y-1]
PL.append([T4,x+1,y-1])
if y>=1:
T6 = own['Matrix'][x][y-1]
PL.append([T6,x,y-1])
so T1 - T6 = neighbor tiles that may or may not exist.
[Neighbor,X_location in matrix,Y_location in matrix]
Height = own[‘Matrix’][X][Y]*.5
