krpano 全景之内置函数 ---asyncloop roundval 等（不定期更新）

loopactions

The actions that will be repeatedly called / executed as long as the condition is true.

doneactions (optionally, asyncloop only)

The actions that will be called when the condition becomes false and the looping stops.

2.基本的函数运算（add、sub、mul、div、mod、pow）

==================================

add(variable, valueA, valueB*)

sub(variable, valueA, valueB*)

mul(variable, valueA, valueB*)

div(variable, valueA, valueB*)

mod(variable, valueA, valueB*)

pow(variable, valueA, valueB*)

Actions for mathematical calculations.

These actions can be used with 2 or3parameters:

with 2 parameters:

add(dst,val1)? =? dst = dst +val1 (like +

=)

sub(dst,val1)? =? dst = dst -val1 (like -=)

mul(dst,val1)? =? dst = dst *val1 (like *=)

div(dst,val1)? =? dst = dst /val1 (like /=)

mod(dst,val1)? =? dst = dst %val1 (modulate)

pow(dst,val1)? =? dst = dst ^ val1

with 3 parameters:

add(dst,val1,val2)? =? dst = val1+ val2

sub(dst,val1,val2)? =? dst = val1- val2

mul(dst,val1,val2)? =? dst = val1* val2

div(dst,val1,val2)? = ?dst = val1 / val2

mod(dst,val1,val2) ?= dst = val1 %val2 (modulate)

pow(dst,val1,val2)? =? dst = val1^ val2

Note - val1 and val2 can be values or variables. When val1 or val2 is a variable then automatically the content of the variable will be used!

//val1 和 val2 是可以为常量或者变量的

Parameters:

variable

The variable where the result of the calculation will be stored**.//生成的结果直接被存储起来。**

When the variable doesn't exists, it will be created.//如果没有定义直接创建一个

valueA / valueB (optionally)

The values or variables for the calculation.

3.roundval

roundval(variable, decimalplaces*)

Rounds the value of the variable to given decimal places (0 when not set).//在小数点后给定指定的数值的位数。如果不设置的话默认为 0

(Note - the variable will be a string internally after rounding) //四舍五入后的内部变量将是一个字符串

Parameters:

variable

The variable to be rounded.

decimalplaces (optionally)

The number of decimal places.

4.txtadd

========

没什么说的，在 destination 位置添加文本，如果多个参数的话就连在一起。

txtadd(destination, txt1, txt2*, txt3*, ...)

The txtadd action can be used to add/connect several texts / values together.

The action can be used with 2 or more parameters. When using only two parameters (destination and a text) then the text will be added to current value of the destination variable.

Parameters:

destination

The destination variable where the connected text will be stored.
