MAXScript101_2.5 Expressions

MAXScript101_2.5 Expressions

布尔运算$box01 - $sphere01

 

 

1. 数值的算术运算请参考MAXScript Reference中的 Number values

 

2. 非数值的算术运算
--字符串相加
"to be " + "or not to be" -- class: string
--物体做布尔运算
$box01 - $sphere01 -- class: geometryClass
--求中点
midpoint = ($obj1.pos + $obj2.pos) / 2 -- class: Point3
--求两点间位移差
delta = $obj1.pos - $obj2.pos -- class: Point3
--从当前位置偏移一个量
$obj2.pos = $obj2.pos + 3 * delta -- also can be written as: $obj2.pos += 3 * delta , same as *=, /=

 

3. 点操作符
$box1.material.diffuseColor.hue

 

4. 比较表达式(Comparison Expression)，返回值为bool型
>
<
>=
<=
==
!=

 

5. 逻辑表达式(Logical Expressions)
逻辑操作符(Logical Operators): and, or, and not, or not
for obj in objects do
(
if classOf obj == sphere and obj.radius < 5 or
classOf obj == box and (not obj.height >= 10)
then
obj.material = smallObjMtl
)

 

6. 转换表达式(Conversion/Casting Expressions)
42.0 as string --
"3.14159" as float / 2
x_angle = ($box.rotation as eulerAngles).x

 

7. 操作符优先级从上到下排列
