嘿，最近我从这里学习使用 ursina 。
但是如果我要添加更多blocks/cubes游戏会滞后很多，
我发现通过组合所有立方体的网格并渲染一个单孔网格，它不会滞后太多但是问题是

I can't find a way to combine the mesh of cubes into one big mesh

如果你想要这是我的代码

def update():
    global block_pick, player, block_pickOriginal
    try:
        if block_pick != block_pickOriginal:
            a = Text(blockL[block_pick - 1], scale=1.5, position=Vec2(-.0, -0.35))
            block_pickOriginal = block_pick
            destroy(a, delay=.5)
    except:
        pass

    # print(player.world_position[2] // .5 // 2)

    # print(round(player.x) // .5)

    if held_keys['left mouse'] or held_keys['right mouse']:
        hand.active()
    else:
        hand.passive()

    if held_keys['q']:
        quit()
    if held_keys['1']:
        block_pick = 1
        grid.texture = grassS
    if held_keys['2']:
        block_pick = 2
        grid.texture = stoneS
    if held_keys['3']:
        block_pick = 3
        grid.texture = woodPlankS
    if held_keys['4']:
        block_pick = 4
        grid.texture = dirtS

    if held_keys['5']: block_pick = 5
    if held_keys['6']: block_pick = 6
    if held_keys['7']: block_pick = 7
    if held_keys['8']: block_pick = 8
    if held_keys['9']: block_pick = 9

    if player.world_position[1] < -100: player = FirstPersonController()

    # print(player.world_position[1])


class Voxel(Button):
    def __init__(self, position=(0, 0, 0), texture=grass_texture):
        super().__init__(
            parent=scene,
            position=position,
            model='assets/block',
            origin_y=0.5,
            texture=texture,
            color=color.color(0, 0, random.uniform(0.9, 1)),
            scale=0.5)

    def input(self, key):
        global voxel

        if self.hovered:
            if key == 'left mouse down':
                punch_sound.play()
                if block_pick == 1: voxel = Voxel(position=self.position + mouse.normal, texture=grass_texture)
                if block_pick == 2: voxel = Voxel(position=self.position + mouse.normal, texture=stone_texture)
                if block_pick == 3: voxel = Voxel(position=self.position + mouse.normal, texture=brick_texture)
                if block_pick == 4: voxel = Voxel(position=self.position + mouse.normal, texture=dirt_texture)
                if block_pick == 5: voxel = Voxel(position=self.position + mouse.normal, texture=coal_texture)
                if block_pick == 6: voxel = Voxel(position=self.position + mouse.normal, texture=glass_texture)
                if block_pick == 7: voxel = Voxel(position=self.position + mouse.normal, texture=iron_texture)
                if block_pick == 8: voxel = Voxel(position=self.position + mouse.normal, texture=gold_texture)
                if block_pick == 9: voxel = Voxel(position=self.position + mouse.normal, texture=diamond_texture)

            if key == 'right mouse down':
                punch_sound.play()
                destroy(self)

for z in range(20):
    for x in range(20):
       voxel = Voxel(position=(x, 0, z))
player = FirstPersonController()

在这个链接 中，我找不到用立方体来做到这一点的方法，我什至可以用游戏中的立方体来做到这一点 bcos 的几何the cubes isn't going to be the same every time

任何帮助，将不胜感激

谢谢！！
