This is an experimental object whose purpose is to test a code that changes parameters (by means of 'GLOB_MODPAR_NAME') in order to keep objects parts unchanged. Once resolved, I intend to apply the concept to other real life objects.
It draws two rectangles. The second rectangle is always the height of the first plus a constant 'gap'.
There is a parameter called 'method', whose value can be 1 ou 2.
If method = 1, the 'B' parameter will be the height of first rectangle (h1=B), so the second rectangle has a height of B+gap.
If method = 2, then ' B' should be the height of the second rectangle (h2=B), so h1=B-gap.
I don't want the heights change when method is changed. Instead, I want the 'B' is recalculated so that the heights remain the same.
For instance, method=1, so h1=B=1000 and h2=1500. When method is changed to 2, then h1 should remain =1000 and h2=1500, but B must change from 1000 to 1500.
I wrote these scripts:
What happens is that 'gap' is added/subtracted TWICE every time I change 'method' (in my example, B goes from 1000 to 2000 instead of 1500 when method goes from 1 to 2).
So I changed the Parameter Script to this:
And the code works as expected. But in the real-life objects I intend to write, it won't be so easy to compensate this difference.
So the question is: why the code within 'IF GLOB_MODPAR_NAME....' is executed twice when I change the parameter only onceand how could I correct this misbehavior?

I wrote these scripts:
| Code: |
| !---- Master Script gap = 0.5 IF method = 1 THEN h1 = B h2 = B+gap ELSE h1 = B-gap h2 = B ENDIF !--- Parameter Script VALUES "method" 1, 2 IF GLOB_MODPAR_NAME = "method" THEN IF method = 1 THEN PARAMETERS B = B-gap ELSE PARAMETERS B = B+gap ENDIF ENDIF !--- 2D Script RECT2 0, 0, A, h1 ADD2 1, 0 RECT2 0, 0, A, h2 DEL 1 |
What happens is that 'gap' is added/subtracted TWICE every time I change 'method' (in my example, B goes from 1000 to 2000 instead of 1500 when method goes from 1 to 2).
So I changed the Parameter Script to this:
| Code: |
| !--- Parameter Script VALUES "method" 1, 2 IF GLOB_MODPAR_NAME = "method" THEN IF method = 1 THEN PARAMETERS B = B-(gap/2) ELSE PARAMETERS B = B+(gap/2) ENDIF ENDIF |
And the code works as expected. But in the real-life objects I intend to write, it won't be so easy to compensate this difference.
