Moving part of an objet with a hotspot

Anonymous

I am trying to put in place an objet that has a 3D form and 2D éléments, the red lines (please see images). I would like to allow the user to move manually the 2D lines in red. The 2D red lines are on itself an objet that is called into the final object.

I have managed to use the ADD2 and allow to enter a distance but I would prefer to let the user freely move that part of the objet (the 3D doesn't move).

So far this is the code that I have to call the 2D lines and move it by the ADD2 command. How could I change so to have a point to manually drag the red lines?

Thank you in advance.

ADD2 0,-AF5_A
        gosub "symbole 2D"

            end

"symbole 2D":

You will have to check the GDL Reference Manual for Hotspots, graphical editing.
If you need to graphically control the symbol position in X and Y axis, you will have to create two parameters for X and Y. Like this:
! Top X
hotspot2 0, pointDistY, unID, pointDistX, 1+128		!BASE (hidden)
unID = unID + 1
hotspot2 -1, pointDistY, unID, pointDistX, 3		!REFERENCE
unID = unID + 1
hotspot2 pointDistX, pointDistY, unID, pointDistX, 2	!MOVING
unID = unID + 1

! Top Y
hotspot2 pointDistX, 0, unID, pointDistY, 1+128		!BASE (hidden)
unID = unID + 1
hotspot2 pointDistX, -1, unID, pointDistY, 3		!REFERENCE
unID = unID + 1
hotspot2 pointDistX, pointDistY, unID, pointDistY, 2	!MOVING
unID = unID + 1

Thanks Paulo for pointing me on the right direction.

I have added to the script. I end out with 2 new hotspots but they stretch the object in X and not just move it.
I read the web page you linked and as far I understood the script in your answer is indicated for this kind of stretching action with a 3 point set, is that the case?

I also noticed that when I create the final objet : a 3D form plus the 2D symbol object, the hotspots end out changing both elements despite being a part of the 2D objet script. Meaning: the 3D form is also stretched.

(I did create two parameters pointDistY and pointDistX.)

This is the 2D symbol script this far. I would appreciate some more imput. Thank you in advance.

If you want to move the 2D symbol, the the hotspots go in the parent object before you call the 2D symbol.

So in your example....

! Top X
hotspot2 0, pointDistY, unID, pointDistX, 1+128		!BASE (hidden)
unID = unID + 1
hotspot2 -1, pointDistY, unID, pointDistX, 3		!REFERENCE
unID = unID + 1
hotspot2 pointDistX, pointDistY, unID, pointDistX, 2	!MOVING
unID = unID + 1

! Top Y
hotspot2 pointDistX, 0, unID, pointDistY, 1+128		!BASE (hidden)
unID = unID + 1
hotspot2 pointDistX, -1, unID, pointDistY, 3		!REFERENCE
unID = unID + 1
hotspot2 pointDistX, pointDistY, unID, pointDistY, 2	!MOVING
unID = unID + 1

Hi Barry, thanks for your help.

First, could you please tell me how to add the script line number ? I don't see the line numbers so I have to count sometimes...

I ended out with the possibility to move the 3D form instead of the symbol. I've tried to change the order of the actions in the script and this is the best I could do as seen on the before and after images attached.

There are also two hotspots apparently: one moves the form the other deforms. I wish I had only one.
Also there is this reference to one old objet AF5 on this line and I am not sure if I should replace it with the name of the parent objet or the 2D objet....
ADD2 0+pointDistX,-AF5_A+pointDistY
I would appreciate if you could take a look at the new script. I am not sure if it's clear that first I created the 2D object and then selected it plus the form to create the final (parent) object.

-------

This is the 2D script in the parent object:

You can't see the line numbers in the GDL editor.
However, place your cursor in any line and press CTRL+L and you will see the line number of that line.
You can then type any line number and ENTER and you will be taken to that line.

You have the hotspot for the X & Y position (pointDistX & pointDistY).
These are two hotspots but scripted so they work as one and move in both the x & y direction.

If you want to move the 2D object, use the hotspot scripts, then ADD2 pointDistX, pointDistY.
Then call the 2D object.
Then DEL one to remove the ADD2 transformation - placing you back at the same position you started at.
Always try to return to the origin.

If you want to move the 3D object (or at l should say the 2D view of the 3D object) then you would place the hotspots script, ADD2 pointDistX, pointDistY, and then call the 3D object and DEL 1.
Don't forget if you are moving the placement of the 3D object in the 2D script, you should also move it in the 3D script so they match.

ADD2 0+pointDistX,-AF5_A+pointDistY

The -AF5_A I got from your original code.
You were ADDing a distance before you placed your object.
I kept it the same and add the hotspot distances to it, so it would remain at the distance -AF5_A when the hotspot values are zero.
If you don't want it you can take it out.


The editable hotspot referencing A is the one stretching the size of the object.
If you don't want it, remove it.


you basic code to place the 3D object and then have a moveable 2D object should be something like ...

CALL 3D_object

! Top X
hotspot2 0, pointDistY, unID, pointDistX, 1+128 !BASE (hidden)
unID = unID + 1
hotspot2 -1, pointDistY, unID, pointDistX, 3 !REFERENCE
unID = unID + 1
hotspot2 pointDistX, pointDistY, unID, pointDistX, 2 !MOVING
unID = unID + 1

! Top Y
hotspot2 pointDistX, 0, unID, pointDistY, 1+128 !BASE (hidden)
unID = unID + 1
hotspot2 pointDistX, -1, unID, pointDistY, 3 !REFERENCE
unID = unID + 1
hotspot2 pointDistX, pointDistY, unID, pointDistY, 2 !MOVING
unID = unID + 1

ADD2 0+pointDistX,pointDistY

CALL 2D_object

DEL 1

Hi Barry,

Thank you very much for your help. The objects are done. Things I will try to do later: texts should be always readable (if the final object is turned) and adjust to scale, and I still dont understand how to manage the point into which the 2D object is placed the first time.

Also, as of yesterday I had only two objects: one parent and one linked. I understood from you last answer that indeed I should have 3: one parent and two linked.

Again, thank you very much.

Do a search in this forum and you will find a few post relating to this problem.

I was just going by what you had in your script sample.
You have the parent object and it calls the 2D (call "objet 2d partiel") which I assume is the circle and lines.
And then you call the 3D object (call "objet 3d partiel") which I asume is the box (as it is in the 2D script it will display the 2D view of that 3D object).
So it just depends if you want to move the lines or the box.
You place the hotspot commands and the ADD2 before the CALL for the object you want to move.
Then DEL 1 after the call to undo the move and place you cursor back to where it was before.

Yes. sooner or later I will try to tackle the text orientation and scale.
Thank you !
