hi all, i am begginer in JA Coding, so i have a question :

it's possible to make the disruptor fire bounce on wall, if yes, how ???

 

thx in advance

You could check out bg_weapons.c and g_weapons.h, don't know about doing this with that gun though

[razorace]

You can't without doing some serious coding changes to the SDK code.

ok, thx for answers, but i have another question : how to remove an item from the player ? because i have made a command to give the jetpack to the player, but how remove it ??

[razorace]

Well, I beleive the jetpack disappears when the player dies.

[Freyr]

if( ent->client->ps.stats[sTAT_HOLDABLE_ITEM] & HI_JETPACK )

{

ent->client->ps.stats[sTAT_HOLDABLE_ITEM] ^= HI_JETPACK ;

}

 

I think that will work.

[alexx860]

didn't work

[razorace]

ent->client->ps.stats[sTAT_HOLDABLE_ITEM] ^= HI_JETPACK;

 

What's the ^= operator? (x = x ^ y) = (x ^= y)?

 

The correct math operator to remove a flag like that is...

 

ent->client->ps.stats[sTAT_HOLDABLE_ITEM] &= ~HI_JETPACK;

[RenegadeOfPhunk]

The ^ operator is Exclusive OR (XOR) - with the following truth table:

 

A B R

 

0 0 0

0 1 1

1 0 1

1 1 0

 

This code:

 

if( ent->client->ps.stats[sTAT_HOLDABLE_ITEM] & HI_JETPACK )

{

ent->client->ps.stats[sTAT_HOLDABLE_ITEM] ^= HI_JETPACK ;

}

 

...would toggle the HI_JETPACK bit to off, if it was on. So actually, even though it's a bit OTT (Razor's code is the more correct and easier way!), this code should actually succeed in turning off that bit.

 

I think the problem may lie in when you are running this code - I don't think you've specified this anywhere. Also, you probably need to clear the EF_JETPACK flag at the same time...

 

i.e.

 

ent->client->ps.stats[sTAT_HOLDABLE_ITEM] &= ~HI_JETPACK;

ent->client->ps.eFlags &= ~EF_JETPACK;

[Azymn]

If you wanna use the same command to give the jetpack as take it away then XORing is the way to go:

 

if( !strcmp(cmd, "givejetpack"))
{
ent->client->ps.stats[sTAT_HOLDABLE_ITEM] ^= HI_JETPACK;
ent->client->ps.eFlags ^= EF_JETPACK;
}

 

That command will give them a jetpack if they don't have one, and take it away if they do. The only problem is if the HI_JETPACK and EF_JETPACK bits get out of sync with each other. =]
