Adding variables to physics entites, and crash

[chillok]

Right, I want to add variables (which represent a state) to entity's. These will be changed based on certain events which happen.

tagged with // chx

I have done this so far:

Code: Select all

struct objectparams_t
{
   Vector      *massCenterOverride;
   int         magnet; //chx
   float      mass;
   float      inertia;
   float      damping;
   float      rotdamping;
   float      rotInertiaLimit;
   const char   *pName;            // used only for debugging
   void      *pGameData;
   float      volume;
   float      dragCoefficient;
   bool      enableCollisions;
};


Code: Select all

const objectparams_t g_PhysDefaultObjectParams =
{
   NULL,
   0, // chx - magnet
   1.0, //mass
   1.0, // inertia
   0.1f, // damping
   0.1f, // rotdamping
   0.05f, // rotIntertiaLimit
   "DEFAULT",
   NULL,// game data
   0.f, // volume (leave 0 if you don't have one or call physcollision->CollideVolume() to compute it)
   1.0f, // drag coefficient
   true,// enable collisions?
};


Which create the params and their default values.

(Also added the getters and setters:)

virtual void SetMagnet( int magnet ) = 0;
virtual int GetMagnet( void ) const = 0;

Now, this is all I added. It builds fine.
When you load the level, I think it calls these but then overrides the values based on a script/code. The game then crashes.

Does anyone have any insight into this shiz?

cant you debug? sure youve overridden the virtual functions?

[chillok]

I hit debug, up comes HL2: Ep , i load a map, crash.

In the dump, it shows me the line, specifically a value which points to the above code (mm, indirectly).

See I dont wish to override anything, I'm attempting to add my own values.


Thanks for reply =D

[zombie@computer]

well, what line in the code? to me its totally unclear what you are trying to do...

[chillok]

Sorry, it was the &params variable which was breaking it, which is the struct above which was initialised.

Regardless, I took a different approach and started using the baseentity class, and it works fine.


[For clarity, what I was trying to do is add a variable to the entities/physicsentity and be able to access/mutate it.]
