A3D_CreateArea

Create four walls around a rectangle on the ground.

stock bool:A3D_CreateArea(
    Float:minX,
    Float:minY,
    Float:maxX,
    Float:maxY,
    Float:minZ,
    Float:maxZ,
    Physic:walls[4],
    worldid = -1,
    Float:width = 0.2
)

Parameters

Parameter	Description	Default
Float:minX	West edge.
Float:minY	South edge.
Float:maxX	East edge.
Float:maxY	North edge.
Float:minZ	Bottom of the walls.
Float:maxZ	Top of the walls.
Physic:walls[4]	The four walls created, south, north, west and east.
worldid	Virtual world they collide in, or -1 for every world.	-1
Float:width	Thickness of each wall, outside the rectangle.	0.2

Returns

• true when the four walls were created.
• false when the rectangle is empty, or the world is full.

Remarks

A stock of the include that creates four static boxes with A3D_CreateStaticBox. The walls stand outside the rectangle, so the whole rectangle stays free inside. The south and north walls run past the corners by width, which closes the corners.

When a wall cannot be created, the walls already created are destroyed and the function returns false. Each wall is a static object of its own, destroyed with A3D_DestroyObject.

Example

Keeps the balls of a game inside a pitch.

static Physic:gPitch[4];

public OnGameModeInit() {
    if (!A3D_CreateArea(1680.0, -2520.0, 1720.0, -2480.0, 12.5, 15.5, gPitch)) {
        print("The pitch could not be walled.");
    }

    return 1;
}

public OnGameModeExit() {
    for (new i; i != sizeof (gPitch); ++i) {
        A3D_DestroyObject(gPitch[i]);
    }

    return 1;
}
