A3D_SetAcceleration

Push a moving physics object with a constant acceleration until it is set to zero.

native bool:A3D_SetAcceleration(Physic:physicid, Float:ax, Float:ay, Float:az);

Parameters

Parameter	Description
Physic:physicid	Physics object to push.
Float:ax	Acceleration on the X axis, in metres per second squared.
Float:ay	Acceleration on the Y axis.
Float:az	Acceleration on the Z axis.

Returns

• true when the acceleration was set.
• false when physicid is not a moving physics object.

Remarks

The acceleration is applied on every step, on top of the gravity, until it is set to 0.0, 0.0, 0.0. It acts as a force of the mass times the acceleration, so every object reaches the same acceleration whatever its mass. An accelerated object never comes to rest.

It suits wind, a conveyor belt or a rocket.

Example

Blows a balloon away to the east.

stock Physic:LaunchBalloon(Float:x, Float:y, Float:z) {
    new Physic:balloon = A3D_CreateSphere(-1, 0.4, x, y, z, 0.1);

    A3D_SetGravity(balloon, -0.5);
    A3D_SetAcceleration(balloon, 1.5, 0.0, 0.0);

    return balloon;
}
