How to make fps higher at a 3d game.

Questions

If you are creating a set of blocks in a kind of wall that won’t move, ie the wall won’t break up into pieces, it’s way more efficient to create the wall as a single 3D block, and tile the texture image on it to create the illusion of separate blocks.

As I said in my post above, the 714 meshes could be reduced to 6. Here’s similar code to what I have above and it uses 6 meshes, one for each side, and runs at approx 60 FPS.

EDIT: Changed code.

function setup()
    m=mesh()
    for x=0,15 do
        for y=0,15 do
            m:addRect(x*42+21,y*42+21,42,42)
        end
    end
    m.texture="Cargo Bot:Crate Blue 1"
    img=image(42*16,42*16)
    setContext(img)
    m:draw()
    setContext()   
     
    m=mesh()
    for x=0,15 do
        for y=0,1 do
            m:addRect(x*42+21,y*42+21,42,42)
        end
    end
    m.texture="Cargo Bot:Crate Green 2"
    img1=image(42*16,42*2)
    setContext(img1)
    m:draw()
    setContext()

    parameter.watch("fps")
    parameter.integer("eyeX",-4000,4000,0)
    parameter.integer("eyeY",-200,200,0)
    parameter.integer("eyeZ",-4000,4000,0)
    parameter.integer("cenX",-1000,1000,-1000)
    parameter.integer("cenZ",-1000,1000,-1000)
    sides={}
    table.insert(sides,side(100,21,100,"top"))
    table.insert(sides,side(100,21,100,"bottom"))
    table.insert(sides,side(100,21,100,"front"))
    table.insert(sides,side(100,21,100,"back"))
    table.insert(sides,side(100,21,100,"left"))
    table.insert(sides,side(100,21,100,"right"))
end

function draw()   
    background(0)
    perspective(100)
    camera(eyeX,eyeY,eyeZ, cenX,0,cenZ, 0,1,0)
    for a,b in pairs(sides) do
        b:draw()
    end
    fps=1/DeltaTime//1
end

side=class()

function side:init(x,y,z,pos)
    v={ vec3(-x, -y,  z),      -- Left  bottom front
        vec3( x, -y,  z),      -- Right bottom front
        vec3( x,  y,  z),      -- Right top    front
        vec3(-x,  y,  z),      -- Left  top    front
        vec3(-x, -y, -z),      -- Left  bottom back
        vec3( x, -y, -z),      -- Right bottom back
        vec3( x,  y, -z),      -- Right top    back
        vec3(-x,  y, -z) }     -- Left  top    back 
    self.ms=mesh()
    tex={ vec2(0,0),vec2(1,0),vec2(0,1),vec2(1,1) }                
    self.ms.texCoords={ tex[1],tex[2],tex[4],tex[1],tex[4],tex[3] }    
    if pos=="back" then
        self.ms.texture=img1
        self.ms.vertices={ v[6],v[5],v[8],v[6],v[8],v[7] }
    elseif pos=="front" then
        self.ms.texture=img1
        self.ms.vertices={ v[1],v[2],v[3],v[1],v[3],v[4] }
    elseif pos=="top" then
        self.ms.texture=img
        self.ms.vertices={ v[4],v[3],v[7],v[4],v[7],v[8] }
    elseif pos=="bottom" then
        self.ms.texture=img
        self.ms.vertices={ v[5],v[6],v[2],v[5],v[2],v[1] }
    elseif pos=="right" then
        self.ms.texture=img1
        self.ms.vertices={ v[2],v[6],v[7],v[2],v[7],v[3] }
    elseif pos=="left" then
        self.ms.texture=img1
        self.ms.vertices={ v[5],v[1],v[4],v[5],v[4],v[8] }
    end
    self.ms:setColors(255,255,255,255)
end

function side:draw()
    self.ms:draw()
end

You could make an if statement when the FPS is less than 40 then smooth graphics is disabled else smooth graphics is enabled.

if FPS <= 40 then
noSmooth() 
else
smooth()
end
