switch function with string

Can I use the switch function with strings too?

For example:

int vehicletype = gettablestr("vehicle",1,2);
switch (vehicletype)
{
case "car":
{
coloryellow(item);
break;
}
case "truck":
{
colorred(item);
break;
}
case "plane":
{
colorgreen(item);
break;
}
}

Thanks a lot!

Congshi,

no you can´t use a string to switch. Please take a look into the Flexsim User Manual (under help within Flexsim). In the section "Writing Logic in Flexsim" you can find information about coding in Flexsim.

Hope that helps!

Good luck

Hi,

No you can only use numbers.

Because you can easily change to C/C++ instead of Flexscript and therefore Flexscript
must be compatibly with C/C++. In C/C++ switch can only take numbers.

Ralf was quicker then me.

Guys,

Here is something interesting to try as an alternative to using numbers.

First, I entered the following in the Global Macros tab in Global Variables:
#define VT_CAR 1
#define VT_TRUCK 2
#define VT_BUS 3

Second, I created a table (name = "Test") with a column of strings and randomly entered in one of the #defines from above.

Third, I placed the following code in a script window and executed it:
for(int row = 1; row < gettablerows("Test"); row++)
{
switch(executefsnode(gettablecell("Test", row, 1), NULL, NULL, NULL, 0))
{
case VT_CAR: msg("TYPE", "CAR"); break; //Could have put 1 instead of VT_CAR
case VT_TRUCK: msg("TYPE", "TRUCK"); break; //Could have put 2 instead of VT_TRUCK
case VT_BUS: msg("TYPE", "BUS"); break; //Could have put 3 instead of VT_BUS
}
}

This will be slower than using numbers because you are calling executefsnode but you don't have to worry about having a cryptic number instead of a sting in your table either.

*I could have used "Car", "car", "CAR", etc. instead of "VT_CAR" for my #define name but I placed the VT ("Vehicle Type") in there so that it would be more unique and less likely to interfere with a variable somewhere.

**Also, I believe that you can use either integers or characters in C++ switch statements while Flexscript limits you to integers.

Good Luck,
Brandon

Hi,

It is correct that in C/C++ you can either use integer or char, but that is because char is treated as number in C/C++ 0 to 255.
