A3D_GetModelBoundingSphere

Find the sphere that holds a model, around its position.

native bool:A3D_GetModelBoundingSphere(modelid, &Float:x, &Float:y, &Float:z, &Float:radius);

Parameters

Parameter	Description
modelid	Model to read.
&Float:x	Centre on the X axis.
&Float:y	Centre on the Y axis.
&Float:z	Centre on the Z axis.
&Float:radius	Radius of the sphere.

Returns

• true when the sphere was written.
• false when the database does not know the model.

Remarks

The centre is an offset from the origin of the model, as for A3D_GetModelBoundingBox. The sphere holds the whole model, so for a round model its radius suits A3D_CreateSphere.

Example

stock Physic:CreateModelSphere(modelid, Float:x, Float:y, Float:z, Float:mass) {
    new
        Float:centreX,
        Float:centreY,
        Float:centreZ,
        Float:radius
    ;

    if (!A3D_GetModelBoundingSphere(modelid, centreX, centreY, centreZ, radius)) {
        return INVALID_PHYSIC_ID;
    }

    return A3D_CreateSphere(modelid, radius, x, y, z, mass);
}
