Hi!
Bug 1: I'm trying to remove a head of an enemy if I shoot at it. To do this I'm using the dbRemoveLimb ( int Object, int Limb ) command.
Here is an example that works:

And here is an example the doesn't work (I am pressing the space key when I run it):

So what's going on there?

Bug 2: My model I'm loading that's being used in the previous bug doesn't have a texture. So most times when I load it, it is black, but sometimes it's red. I'm pretty positive that it changes randomly and if it doesn't then it's changing for stupid reasons like adding an if statement some where that has nothing to do with the model.

Bug 3: Sometimes when the head of the model does get removed the vertices are all over the place. It's almost like the vertices in the head are being moved in all random directions when ever I do dbRemoveLimb.

Bug 4: Occasionally when I remove a limb I get an unhandled exception error.

So does anyone have ideas on why this is happening?

EDIT: dbOffsetLimb works but not dbHideLimb or dbRemoveLimb
EDIT2: I found the source of the bugs 1, maybe 2, and maybe 4. The problem is, is that dbRemoveLimb does not do anything after dbSync ( ) or dbFastSync ( ) has been called.
EDIT3: When dbRemoveLimb is called after a dbSync ( ) or dbFastSync ( ) the limb is being removed but not being update on the screen. I tested this with:
(It did not exit meaning the limb WAS removed, but it was still there on the screen)

Bug one:you may want to try


Bug 2:be sure that the models textures are in the same directory as the model(eg. .dds,.jpg,or .png file ect.)

if im not mistaken dbRemoveLimb simply detaches the specified limb rather than deletes it from view as i believe you want. i recommend trying dbHideLimb().

Answer to Bug 1: ( dbSpaceKey() == 1 ) and ( dbSpaceKey() ) are the same thing.

Answer to Bug 2: The model is loaded

As for the function of dbRemoveLimb, if I call it before a dbSync() or dbFastSync() it's completely deleted but I'll look into the detaching idea. And I've always wanted to use dbHideLimb() but it never works, not sure why but it doesn't.

Show us a proper example of this including the media? It's quite hard to test issues like the random colour issue without any media, as I've not noticed anything like this before. Also what version are you using?

Heyufool: ( dbSpaceKey() == 1 ) is not the same as ( dbSpaceKey() ). For when putting the command dbSpaceKey() it returns a value of 1 if it is pressed and 0 if not, so in the if function you need the == 1.

if ( dbSpaceKey() ) {...} ---> if (the condition) is true {...}

and since every value in C++ is true except the zero, when dbSpaceKey() returns 1 the condition will be true, else if it returns a zero (false value) the condition will be false.

which means that (dbSpaceKey()) and (dbSpaceKey()==1) are the same.

Nope, one checks if the value isn't 0x0, the other checks if it is 0x1. In this instance dbSpaceKey() returns either a 0 or 1 so there is no semantic difference. The former is very useful in many cases, particularly when dealing with pointers and you wish to check if it isn't NULL.

I'm using version 7.4 and I'm making a small example now, will edit when done.

Edit: Ok I attached the example to this post and it uses the exact same model that I used when this problem occurred.

READ THIS:
1. Do not hold space when the program starts, otherwise the head will be removed successfully.
2. Press space when the program is running to see that the head is not removed.
3. Comment out the "if ( dbSpaceKey ( ) )" line to see that the head is successfully removed.

Interesting, it appears GDK fails at memory management. If I change the limb to be removed to 2 then it turns red for no reason. It'd be best to post what you just posted on the bug thread so anyone confirming it can easily test it themselves.

Thanks for checking it out! And I did post a bug report with the example

I tested and it worked fine for me minus the red (which im almost certain can be fixed by adding a texture)

Huh really? Which dark GDK version are you using?
