New page

== Components ==
The component portion of an expression is what will be affected. For example,
= 0 [Instructions]
will take the value of the [Instructions] portion, and push it onto the X position of the Expression bone, while;
= 4 [Instructions]
will take the value of the [Instructions] portion, and push it onto the Y rotation of the bone.

== Instructions ==
Instructions are the math portion of expressions. The following operations are allowed:

=== Number ===
n [value]
The '''n''' instruction pushes a number to the stack, for example:
= 6 n 1
sets the X Scale of the bone to 1

=== Variable ===
v [variable]
The '''v''' instruction gets a variable, then pushes it to the stack. The variable can either be:<blockquote>[Component].[Bone] (eg, 4.j_kao_wj, 2.kl_mune_b_wj, 6.j_ude_l_wj)

or

the '''t''' instruction (time elapsed) </blockquote>For example:
= 1 v 4.j_kao_wj
This would set the Y position of the bone to the Y rotation of j_kao_wj, or:
= 2 v t
This would set the Z position of the bone to the value of time elapsed

=== Function ===
f [function]
The '''f''' instruction gets the value on the stack, applies the function, then pushes the value. The function used can be:
{| class="wikitable"
|+
|neg
|Negate the value
|-
|sin
|[[wikipedia:Sine_and_cosine|Sine]] function (in degrees)
|-
|cos
|[[wikipedia:Sine_and_cosine|Cosine]] function (in degrees)
|-
|tan
|[[wikipedia:Trigonometric_functions#tangent|Tangent]] function (in degrees)
|-
|abs
|[[wikipedia:Absolute_value|Absolute Value]] function
|-
|sqrt
|[[wikipedia:Square_root|Square Root]]
|-
|av
|Multiplies value by 0.1
|-
|floor
|Outputs the [[wikipedia:Floor_and_ceiling_functions|floor]] (lowest integer) of a value
|-
|ceil
|Outputs the [[wikipedia:Floor_and_ceiling_functions|ceiling]] (highest integer) of a value
|-
|round
|[[wikipedia:Rounding|Rounds]]<nowiki/>the value
|-
|asin
|[[wikipedia:Inverse_trigonometric_functions|Inverse Sine]] function
|-
|acos
|[[wikipedia:Inverse_trigonometric_functions|Inverse Cosine]] function
|-
|atan
|[[wikipedia:Inverse_trigonometric_functions|Inverse Tangent]] function
|-
|log
|[[wikipedia:Logarithm|Logarithm]] function
|-
|exp
|[[wikipedia:Exponentiation|Exponentation]] function
|-
|rand_0_1
|Unimplemented, makes value 0. (It is meant to randomly generate between 0 and 1)
|}
For example:
= 0 v 1 f av
would set the X position of the bone to 0.1 (since the 1 is multiplied by 0.1)

=== Secondary Functions ===
g [function]
The '''g''' instruction gets two values from the stack, applies the function provided, then pushes the result. The function used can be:
{| class="wikitable"
|+
| +
|Adds the values
|-
| -
|Subtracts X from Y
|-
|*
|Multiplies the values
|-
|/
|Divides X by Y
|-
|%
|Takes a portion of X by Y
|-
|==
|Outputs 1 if values are equal, else 0
|-
|>
|Outputs 1 if X is greater, else 0
|-
|>=
|Outputs 1 if X is greater or equal, else 0
|-
|<
|Outputs 1 if X is lesser, else 0
|-
|<=
|Outputs 1 if X is lesser or equal, else 0
|-
|!=
|Outputs 1 if values are not equal, else 0
|-
|&&
|Outputs 1 if both values are 1, else 0
|-
|<nowiki>||</nowiki>
|Outputs 1 if one value is 1, else 0
|-
|min
|Outputs the lowest value
|-
|max
|Outputs the highest value
|-
|fmod
|Divides X by Y, and outputs the remainder
|-
|pow
|X to the power of Y
|}
For example:
= 6 n 1 n 3 g +
would set the X scale of the bone to 4 (since it adds 3 and 1)
