A3D_SetFriction

Set how much a physics object grips what it touches.

native bool:A3D_SetFriction(Physic:physicid, Float:friction);

Parameters

Parameter	Description
Physic:physicid	Physics object to change.
Float:friction	Friction, 0.0 for ice and about 1.0 for rubber. Starts at 0.5.

Returns

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

Remarks

The friction of a contact is the square root of the product of the frictions of both bodies. The map, players, vehicles and actors have 0.2, so an object of 0.5 slides on the map with about 0.32. An object of 0.0 slides on everything as on ice.

It works on every physics object, static ones included, which makes slippery floors and ramps.

Example

An icy ramp that crates slide down.

public OnGameModeInit() {
    new Physic:ramp = A3D_CreateStaticBox(4.0, 10.0, 0.3, 1700.0, -2470.0, 14.5, 20.0, 0.0, 0.0);

    A3D_SetFriction(ramp, 0.0);

    return 1;
}
