Hi all
I'm in the middle of creating my own level creator but I've hit a bit of a problem I can't seem to solve and hoping someone can help.
basic my editor is made of single meshes connected together using AddMesh but to optimize my my level i use Fitmesh and a copy of the original Mesh to create low polygon version but i can't seem to figure out the maths for UV to stay the same size as the Added meshes. and there is the problem.
here is the example.
Global FPS_Oldtime, FPS_Newtime, FPS_Ticks
Global FPS_Current,FPS_Final
Global FPS_SampleRate = 5 ;Take a sample every N ticks
Global FPS_Samples = 10 ;Samples to average (res of the average)
Global FPS_BufferIndex = 1
Global FPS_Font
Dim FPS_Buffer(10)
