How to hange A & B values of object with an IF script?

[Bilkins]

Hi,

This might be a simple question, but I've not been able to find anything that helps me.

What I would like is quite simple - make A and B have different preset values that can be toggled.

Say I want to make a rectangle, but I want it to have preset dimensions selectable from a list. In my head it should work like this, but it doesn't. Any suggestion would be welcome.

2D

Rect2 0,0,A,B

END

PARAMETERS:

VALUES "size" "min", "medium", "max"

IF "size" = "min" THEN
PARAMETERS A=2
PARAMETERS B=2*2
ENDIF


IF "size" = "medium" THEN
PARAMETERS A=3
PARAMETERS B=3*3
ENDIF


IF "size" = "max" THEN
PARAMETERS A=5
PARAMETERS B=5*5
ENDIF

First I would ...

LOCK "A", "B"

So they can not be changed by the user.

Then in your parameter script you should always set the value of the parameter first and then set the actual parameter.

So ...

IF "size" = "min" THEN
A=2
B=2*2
PARAMETERS A=A, B=B
ENDIF

Hi Barry,

Thanks for the reply. That doesn't affect the A or B values, they are still 1000 like default.

Hi Barry,

I tested it too, but every rect2 is always 1.00/1.00 and not of the A and B size..... !?

With Lock "A" and "B"... doesn't matter.....

Sorry, I just copied & pasted your script.

Should be

IF size = "min" THEN
A=2
B=2*2
PARAMETERS A=A, B=B
ENDIF

Without the quotes around the size variable.

And something like that ?:

VALUES "size" "min", "max"

LOCK "A", "B"

IF GLOB_MODPAR_NAME ="size" and size = "min" THEN
A=2
B=2*2
PARAMETERS A=A, B=B
ENDIF

IF GLOB_MODPAR_NAME ="size" and size = "max" THEN
A=5
B=5*5
PARAMETERS A=A, B=B
ENDIF

What does a VALUES{2} command do when used with A or B? I have never tried it with any of the 3 base dimensions. You could then have a dropdown that tells you your values for each option without needing to open the settings dialogue.

Thanks for the reply to both you and @Barry Kelly !

Can't believe it was something as simple as unnecessary quote marks breaking the script, but I'll take heart that I at least was on the right track.

What's the added benefit of adding this to the script?

IF GLOB_MODPAR_NAME ="size" and size = "max" THEN

[Bilkins]

Good suggestion, that is actually more suitable for my intended use (parking space object with different A & B dimensions based on a variety of parameters).

This script works:

VALUES{2} "size" 2.0, "min", 
5.0, "max"

VALUES{2} "width" size*2, "minwidth", 
size*5, "maxwidth"

LOCK "A", "B"

A=size
B=width
PARAMETERS A=A, B=B

But I would ideally like VALUES{2] for B to be governed by VALUES{2] of the A-dimension. I'm not sure if that is possible? I can't seem to find the right parameter types to use.

VALUES{2} "size" 2.0, "min", 
5.0, "max"

VALUES{2} "width" size*2, "minwidth", 
size*5, "maxwidth"

LOCK "A", "B"

IF size= "max" THEN 
width = "maxwidth"
ELSE
width = "minwidth"
ENDIF

A=size
B=width
PARAMETERS A=A, B=B
