Accessing items

[wizardmachine]

Hi again!

I'm trying to do a boolean function to return true/false depending on self's owning an item or not:

if (items.Contains(itemIndex))
{

// do something!

}

However, I'm failing to see how 'items' actually work. What would be the usual way to check if a weapon is already in the items list? It does kind of look like a list or an array but not really so I'm slightly confused (I'm looping through all .qc files trying to see if I can find some line that performs a similar check but no luck so far). Also my background is C#, JS and Python, so no C or C++ xpPoints at all.

why do you weant to return a boolean??

float() = ... etc...

....

quake uses touch. function to check

void () somecrazytouch  =
{
if (other.classname != "player") //
return;
if (other.items & self.items) // self.items or "items" that item is , sorry for my english
return;

etc...

so the correct way to check is very simple

if (player.items & somentity.items) // or (player.items & IT_SOMEITEM...
//do something
else
//do another thing

I simply wanted to create some custom function to help keep my coding clean, that's why I wanted to write some boolean returning function. Just a thought, could be an int returning function or whatever.

I'm not really sure I get what you mean. What kind of check does the below do:

if (player.items) {}

I want to check, for example, whether player owns the shotgun or not:

if (player.items && IT_SHOTGUN) {}

Would the above be correct?

Also, I found in weapons.qc the following piece of code inside function W_ChangeWeapon:

if (!(self.items & fl))
{

// don't have the weapon or the ammo

sprint (self, "no weapon.\n");

return;

}

but I'm not sure I fully understand it. Variable 'fl' is assigned to one of the weapons, and then it checks !self.items & fl which looks quite similar to the check you suggested. I'll go for it and report back.

Thanks!

if (person.items & IT_ROCKET_LAUNCHER)

Just like you suggested, works like a charm (just realized it's pretty much the same structure as in that weapons.qc function).

Thanks again for your input.

You can't check bits with logical operators (&&, ||, etc). You need to use bitwise operators (&, etc)
