Damageable objects in SCASM

[rhumbaflappy]

I had a request for a simple SCASM example for a damageable library object for CFS2.


A damageable object in CFS2 is a library object. It can be easily made in SCASM code:

Header( 1  N90:00:00.00 S90:00:00.00 E180:00:00.00 W180:00:00.00 )
LatRange(  S90:00:00.00  N90:00:00.00 )

; ----------------------------------------
; Library Object #1
; ----------------------------------------

;//////////////////////////////////////////ObjID is a unique GUID number to identify the library object

ObjID(  2C1D3FFB  4259FA73  4B77FAA3  D3FB5C50  )


;//////////////////////////////////////////SIZE and SCALE should be available from the code????
LibObj(
    PWR   0
    SIZE  10
    SCALE 0.5
    TYPE  0
    NAME   "inf_rhumba_object"    )


    IfVarAnd( :_Undamaged_code 0024 0040 )

    BGLVersion( 0732 )

Dick,
Many thanks for starting this thread off.

A few questions;

To get to the sca situation (as above) do you create two separate models (one undamaged and one damaged), then sca them, to get the info, then combine the sca's to create the combo sca example as above? Do you then combine the two models to create one 2-LOD (undamaged and damaged) model?

Or just create a 2-LOD (undamaged and damaged) model bgl-then sca that, then pick the separate sca sections for each model and create the above combo sca? Or?

Where do the DP boxes and boxmaps come into it?

Cheers

Shessi

[rhumbaflappy]

Hi Shessi.

Yes, create two objects. Then it's pretty much cut and paste from there on.

Try it out with simple models first, then you can use more complicated models.

Dick

[Shessi]

Ok then Dick, thanks.

1) I separately created a simple coloured cube (undamaged object) and a coloured sphere (damaged object).
2) I sca'd both of these.
3) I then went to replicate your posted sca, but.....

1) The initial Header and Latrange at the top, is that the Header and Latrange from the undamaged or damaged object?

2) Can I create any unique GUID number, I use Matts Scasm Editor to create a unique code.

3) You say that size and scale should be from the code, and then ????, where does he scale come from?

4) IfVarAnd( :_Undamaged_code 0024 0040 ) where does this code come from, as neither of the sca'd objects I did (FSDS2.4) have this in the sca?

5) Does the order of the sca text have to be damaged object first then the undamaged object?

6) After getting the above combo sca sorted, do you then combine the two objects as a multi LOD object and create a combo .bgl from that?

7) If that is the case doesn't the code change so that it won't match the hand edited combined sca? Or is the code still correct as it is amde with the same objects?

8) As before, where do the DP boxes and boxmaps come into it?

Sorry for lots of questions! I do work with scasm, and understand the fundementals, but this is whole new ballgame to me, so appreciate your time and answers.

Cheers

Shessi

[rhumbaflappy]

1) The initial Header and Latrange at the top, is that the Header and Latrange from the undamaged or damaged object?

This header is for the object library BGL you are creating. You want the objects to be place-able anywhere in the world.

2) Can I create any unique GUID number, I use Matts Scasm Editor to create a unique code.

Yes. You need to create a unique number for each library object... in this case the object is damagable, but one number for both parts.

3) You say that size and scale should be from the code, and then ????, where does he scale come from?

In the example code, the size is 10, and the scale is 0.5 ( the scale is usually 0.5 for CFS2 and fs2002 objects ). The actual object size is 5 meters ( 10m x 0.5 ).

4) IfVarAnd( :_Undamaged_code 0024 0040 ) where does this code come from, as neither of the sca'd objects I did (FSDS2.4) have this in the sca?

This is the conditional code that displays the damaged model. :_Undamaged_code is the condition failure's jump label, 0024 is the damage variable for CFS2 objects, 0040 ( decimal 64 ) is the universal bitwise "flag" for damage.

5) Does the order of the sca text have to be damaged object first then the undamaged object?

Yes, because on failing the conditional IfVarAnd test, you jump over the damage code and display the undamaged model.

6) After getting the above combo sca sorted, do you then combine the two objects as a multi LOD object and create a combo .bgl from that?

No. You are creating an object library BGL. ( Each model could have LODs if desired... LOD = level of detail, and is triggered by how much of the screen's viewport is taken up by the object. )

7) If that is the case doesn't the code change so that it won't match the hand edited combined sca? Or is the code still correct as it is amde with the same objects?

This is where you're getting mixed up. A damageable object is a library object that has 2 conditional states.

8) As before, where do the DP boxes and boxmaps come into it?

In the example, I named the object "inf_rhumba_object", so the DP file needs to be inf_rhumba_object.dp, and that text file goes into the OBJECTS_DP folder. I'd look at the .dp files for examples of what you might want for the damage ( effects, etc...)


Dick

[Shessi]

Dick,
Appreciate your patience and time...

Ok, got all that. I do understand the idea of a condition state and it being controlled and triggered by damage boxes and a DP.

Regarding Q6. I trying to get clear in my head is the intial building of the models to then create a damageable bgl. I have created one model which is the undamaged version and a separate model being the damaged version. These have been separately sca'd, to create the sca info. Is this incorrect, or should the model be created as one, with both the damage and undamage models already together in it?

In FSDS or Gmax are they separate models within the same model (almost like LODs) or are they actually physically combined within each other, so they are as one, and the natural default view is the conditional IfVarAnd test undamaged model and the DP triggers the viewing of the damaged model. (This is why I was asking, when are they combined to create one model?).
I know this may sound obvious, but I'm used to creating mdls with separate LODs which are triggerd by distance.

Cheers

Shessi

[rhumbaflappy]

I have created one model which is the undamaged version and a separate model being the damaged version.

They are separate models. You just need to cut and paste the appropriate SCASM code to combine into a SCASM library.

Each separate model can have distance LOD code as well, if desired.

Dick

[Shessi]

Ahh I'm seeing it now (I think!). So after combining the sca for the two models (undamaged and damaged), you then convert this combined sca back into a bgl using a sca editor (I use MDLC) to create the model/bgl manually?
I was thinking that you mirrored what was done in the sca with what was done in FSDS/Gmax, but in fact you're using the separate models just to supply info for the sca's, to then build the combined sca, and then make the bgl from that.

What do you use for making bgls?

Shessi

[rhumbaflappy]

You don't need a SCASM editor. Use a text editor. Notepad works fine.

Drop the text file onto SCASM.exe to make the library BGL, or use the command line. I think the latest version of SCASM is v89. Note that this is a library BGL and not a placed object. To place it you need to make a placement BGL, just as you would place any default scenery object.

Dick

[Shessi]

Ok, got that.


I wanted to make damageable placed objects ie structures etc. So to make a placed damageble object/item/structure, just make the object but with the correct location co-ordinates, and then make the damageable bgl from that?

Shessi

[rhumbaflappy]

Probably the best way to show you exactly what to do is for you to zip and attach 2 SCASM objects in a post for me. 2 simple objects... say a cube and a flattened cube. Make them textured and attach the textures as well.

I believe you use FSDS 2.? to make the objects, and FSDS will export SCASM code for us... that's what we want.

I'll show you what we want to copy from the objects, and what we add to the code to produce a damageable library object from that.

Dick

[Shessi]

Here you are, as requested see attached, thanks.

Could you just answer, for damageable objects etc I want to place as scenery. Create undamaged and damaged objects, with the location co-ordinates set in FSDS the same for both, then combine the sca, set a DP for it, and place in the scenery?

This give us a library object that can be placed anywhere in the world.

Compare the damaged and undamaged code to the 2 original objects' code.

Each object starts at:
BGLVersion( 0800 )

Each object ends at:
Return

(... which is found just before the :Exit in the original objects' code. )

In CFS2 you cannot damage an object unless it is of the damagable type, has a .dp profile, and is placed via mission builder ( for a mission ) or by a GSL patch, for global scenery.

A damagable object is a library object.

They can be placed as any other library object. If you place it by the "normal" FS placement code, you can see it, but not damage it.

Thanks Dick, I'm now digesting that and trying a few things....

I'll get back to you.

Dick,
Just when I was getting to grips with hand editing, good ol' Allen comes along with his tutorial and batch file tools. I had just made a few things with hand construction, so now I know (doesn't seem so complicated!!). It's even easier with Allen's tools, automatic!

Anyway, many thanks for the time and explanations, finally one more thing learnt. Here is what I made for a practice. A sub/damaged sub, simple mission, great fun!
