Flexsim uses just four variable types. Each of the four types can also be used in an array structure. The following explains each of these types.% f/ j. S) \/ a0 t; n* F% n% \ r6 w% p

flexsim中有4种类型的变量：int,double,string,treenode。treenode指的是flexsim中的一个节点或者一个实体。 3 R: P* |- _2 U " R/ c5 t' X& n, d7 I' h4 w1 L8 Zcurrent<no parentheses> ; }9 w/ o6 `* s$ S9 R% E8 g C

Deprecated. This should not be used as a special command with the setcurrent command anymore. Instead, declare a treenode variable type as current, then use current in your code as any other variable type. 0 a8 [: w% P. y k' a2 a
不建议使用。current和setcurrent不应再被用作命令。如果需要设置某实体为当前实体，应先声明一个名为current的树节点型变量，然后在代码中引用该变量。7 q9 O8 v! ^0 q, u. z; d+ _

This command returns the node with object data attached to it that is the start of the sub-tree that thenode is in. In other words, it returns the object node that contains thenode.* \4 d* f1 N* t3 D- v3 K# @
This command is used in most code fields and trigger fields to set the access variable current. In these fields, c references the node that contains the code, and ownerobject(c) references the object that "owns" that node. 7 m- Y* r# X/ d- j8 U) M: k该函数返回参数节点所在的实体。 f# w4 R' r0 R2 \ E

This sets objname to the name of the object that contains the node referenced by c. The c usually refers to the node where the code is being written.
treenode current = ownerobject(c);

This command is used to reference the active node during a function's execution. ! {3 D: ~! U- m

不推荐使用。port和setport都不应再作为命令来使用。如果在代码中需要使用端口,需要声明一个名为port的整数型变量，然后在代码中直接使用port作为变量。作者: 天性518 时间: 2013-9-17 13:56 1#zorsite& C5 Y/ J3 o- a4 h6 w% R
