Tutorial by djbozkosz: Destructible Objects

Hi, I wrote a short ” data-emoticon=”” srcset=”/wp-content/uploads/invision_emoticons/smile@2x.png 2x” width=”20″ height=”20″> tutorial, how to create valid destructible objects.

Requirements: Zmodeler, Mafia World Editor and some Hex Editor

At first, something about this objects:

These models have levels of destruction, which are stored in separate models with “_cn” suffix.

Eg: my_model.4ds – non destructed model

my_model_c1.4ds – first level of destructed model

my_model_c2.4ds – second level of destructed model

… to n as:

my_model_cn.4ds – n level of destructed model, where n is integer number greater than 0

In mission, model must be placed as Model Object and to it must be linked primitive collision(s) (eg. XTOO 😎 with material 41. Then, on hit event, the model will be changed to …_c1 and its subobjects will be physical.

Practise:

1. In Zmodeler create repaired model (objects can be merged to one) and export it into models folder.

Note: If you’re changing some old model, which can has lightmap (eg. xbarel 1.4ds, etc.), change name of old object in the model.

2. Then create destroyed object (1st level) with separated parts to own objects in the model. Export model to models folder with same name and suffix _c1. If you’re creating more levels, objects through the models must have identical names.

Note: dummies in the _cn models aren’t importamt.

3. Open mission in Mafia World Editor and insert new Model into scene2.bin file.

4. Create XTOOB colision and link (Parent value) to Model object. Set material to 41.

5. Save mission and close MWE.

6. Then, you have to specify physics properties into _cn models for every object. Every object in the model can have parameters string, which is located behind object name. Before text string is byte with legth of follow string (hex value), which you have to correctly calculate (look at picture).

Follow list describes physics parameters:

Physics parameters are bordered by ; character.

Standard physics have three parameters: M, N and I

M: mass in kilograms

N: type of physics – some unknown values, like: 15, 17, 22, etc…

I: sound (identical as in BScriptView for Physical Objects)

– 0: grenade

– 1: box

– 2: barrel

– 3: recycle bin

– 4: sign

– 5: paper box

– 6: wood

– 7: metal plate

– 8: small gun 1

– 9: small gun 2

– 10: wood plank

– 11: metallic thing

– 12: big gun

– 13: light on car

Example: ;M200N22I13; with length: 0C (in hex)

There are some extra parameters:

X: special

– 1G: glass

– 1H: hydrant

– 1EF: explosive with fire and light

These params are alone in the definition, eg: ;X1G; ;X1EF; etc.

X with value destribes resistance on next destruction level, eg: ;X200M50I2N22+;

+ as suffix is obligatory to link model to next _cn level. Objects in the _cn models must have identical names.

. (dot) have unknown function

Z: object will be solid – without physics

At the end, some expamples of physics definitions:
