Types & Variables

Primitive types, handles, null and type rules.

Primitive types

Type	Description
`int`	64-bit signed integer (decimal or `0x` hex)
`float`	64-bit floating point
`string`	UTF-8 text
`bool`	`true` / `false`
`array`	Ordered list
`map`	String-keyed dictionary
`null`	Absence of a value

Handle types

Callback parameters can be typed as engine handles. Natives still take plain integer ids.

knight

player::death(int playerid, Player killer, int reason) {
    if (killer != null) {
        SendClientMessage(playerid, "You were killed by {PlayerName(killer)}.");
    }
};

Optional annotations

knight

let score: int = 0;
let speed: float = 1.5;

Checking types at runtime

knight

let v = GetPlayerMoney(playerid);
if (is_number(v)) {
    Log("money is a number: " + str(v));
}
Log("type is " + typeof(v));
