Numeric expressions and literals
The numerical rules for maxScript is similar to C/C++.
numbers entered without a decimal are integer and follows integer mathematical rules.
7/2 is 3 (not 3.5)
8/3 is 2 (not 2.667, note the truncation, not rounded up)
if an expression contains both integers and floating point, result is a floating point value
8.0/3 is 2.667
expressions are evaluated according to order of expression rules and propagated in the same manner. In otherwords, follow order of operator rules, results are evaluated one operator at a time.
2.0 + 8/3 is 4.0 (8/3 is 2, add 2.0 to it gives 4.0)
operators:
| operator | what it does | example (int only) | example (float/int) args |
|---|---|---|---|
| + | addition | 3+2 is 5 | 3.2+2.0 is 5.2 |
| - | subtraction | 5-3 is 2 | 5.0 - 2 is 3.0 |
| * | multiplication | 6 *2 is 12 | 2.0 * 2.0 is 4.0 |
| / | division | 8/3 is 2 | 8.0/2 is 2.667 |
| ^ | exponent, base ^ power | 2^3 is 8 | 4 ^ 0.5 is 2 (remember power of 0.5 is same as squareroot). 3 ^ 1.5 is 5, 3.0 ^ 1.5 is 5.19615 |
string literals:
string literals are enclosed in double quotes
"this is a string literal"
strings can be concatenated with + operator
"this is " + "added together with + operator"
results in
"this is added together with + operator"
boolean literals:
true
false
on -- true
off -- false
vector literals
as max deals in 3D, you will see a lot of vectors used in the code. a vector is declared as 3 comma separated values within []. For example, suppose you wanted to place an object at position x=0, y=0, z = 10, you would set the pos parameter to [0,0,10]
[1,2,3]
