Casting

Some object types support casting, some require manual, and some is done automatically.
As of writing only IPostal3Script@ and CBaseEntity@ are capable of some sort of casting.

Manual Casting

Example(s)

// From CBaseEntity@ to CP3Weapon@
CBaseEntity@ pointer;
CP3Weapon@ pWpn = cast<CP3Weapon@>(pointer);


// From IPostal3Script@ to MyClass@
class MyClass : IPostal3Script 
{
    // Content here...
    ...
}

MyClass@ ToMyClass(CP3SObj@ ptr)
{
    IPostal3Script@ class = GetScriptObj("MyClass", ptr);
    if (@class == null)
        return null;

    return cast<MyClass@>(class);
}

// Rough example of how this would look like...
void SomeFunction()
{
    CP3SObj@ self;
    if (@self == null)
        return;

    MyClass@ class = ToMyClass(self);
    if (@class == null)
        return;

    ...
}

From	To	Note(s)
IPostal3Script@	[class]@	Script module, class
CBaseEntity@	CParticleSystem@	n/a
CBaseEntity@	CP3SObj@	n/a
CBaseEntity@	CP3Weapon@	n/a
CBaseEntity@	CP3Player@	n/a
CBaseEntity@	CAI_Hint@	n/a

Auto/Implicit Casting

The objects below also support manual casting, but normally unnecessary.

Example(s)

// CBaseEntity@ to EHANDLE and vice versa
EHANDLE handle;
CBaseEntity@ pointer = handle;
EHANDLE newHandle = pointer;

// CP3Player@ to CBaseEntity@
CP3Player@ pPlayer;
CBaseEntity@ pEnt = pPlayer;

// CP3Weapon@ to CBaseEntity@
CP3Weapon@ wep;
CBaseEntity@ ent = wep;
