因此，对于一个学校项目，我需要建造一个可以发射炮弹的坦克。我在佳能的顶端有一个物体（圆柱体）（使其看起来像佳能的内部）。该对象也是我拍摄外壳的起点。我的许多对象名称可能都是法语的，为此感到抱歉。
这是有问题的物体
interieurcanon=cylinder(radius=1.5,pos=(63.1,23.5,0),axis=(1,0,0),color=(0,0,0))
我所有的旋转运动都很好，除非当我尝试在另一轴然后x上降低或升高我的佳能时。从这一点来看，它看起来很像nothing out of ordinary
这是海拔的代码：
if clavier == "up": #and interieurcanon.pos.y <= 54 and tir == 0: #elevation canon haut
canon.rotate(angle=pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
pivot.rotate(angle=pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
fboulet.rotate(angle=pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
interieurcanon.rotate(angle=pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
if clavier == "down": #and interieurcanon.pos.y >= 23.5 and tir == 0: #elevation canon bas
canon.rotate(angle=-pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
pivot.rotate(angle=-pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
fboulet.rotate(angle=-pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
interieurcanon.rotate(angle=-pi/64,axis=(0,0,abs(bcanon.axis.x)),origin=pivot.pos)
由于某种原因，interieurcanon是唯一不会跟随这两个if中其余对象的对象。
这是我所有代码的链接：（第一部分是相关的战车）
