way to make boat rotate and move at the same time with a rigidbody and addforce ?
hi i have boat and i want any way to make boat rotate and move at the same time with a rigidbody and addforce how can i change ur code
thanks a lot
using UnityEngine;
public class BlockMovement : MonoBehaviour { public GameObject cube; public float speed = 50f; public float rotationSpeed = 50f; public float minRotation = -45f; public float maxRotation = 45f;
void Update()
{
float deltaTime = Time.deltaTime;
float horizontalInput = Input.GetAxis("Horizontal");
if (horizontalInput != 0f)
{
float deltaMovement = horizontalInput * speed * deltaTime;
cube.transform.Translate(new Vector3(0f, 0f, deltaMovement));
}
bool isTurningLeft = Input.GetKey(KeyCode.Q);
bool isTurningRight = Input.GetKey(KeyCode.E);
if (isTurningLeft && !isTurningRight)
{
cube.transform.Rotate(Vector3.left * rotationSpeed * deltaTime);
}
else if (!isTurningLeft && isTurningRight)
{
cube.transform.Rotate(Vector3.right * rotationSpeed * deltaTime);
}
}
}
I just started trying out boat-Physics in Unity, and am finding only complicated (physics-based) methods shown online. Although those are great for boat-simulators that need realistic calculations, I wanted something simpler (quicker and less processor-intensive too) so I ended up building a basic boat-system, one that so far only uses 6 lines of code (2 per script) to control, sway and rock the boat. So here's a simpler (and fairly realistic looking) 'boat effect' to simulate the 'bobbing' and 'swaying' of a ship at sea: Here's three simple scripts, one (boatRock.cs) adds a rocking motion the length of the ship, and the other (bostSway.cs) adds a lesser 'horizontal twisting', and boatSail moves the boat forward at a set speed. Put the 3 scripts together on your BOAT object, and the values can be altered from script according to the water conditions (e.g., a storm). Then set the Main Camera as a child of the BOAT so it follows the BOAT. Here's the 3 scripts, and also I included a starter 'pirate scene' to see how it is set up, and to help anyone learning Unity. I have tried the Mesh-modifier methods and some hinge-joint methods, but dealing with rigidbodies and colliders an be glitchy in Unity, and I got great results so far so I thought I'd post them. One note, I didn't set up any mesh-modifier or mesh-filter yet to make the waves, I am still trying to find a simpler method of making waves in Unity.

Here's the example project with a ship scene to get anyone started: http://www.mediafire.com/file/bd2pohbb794d461/BoatSceneExample1.unitypackage
This method was set up as simple as possible for learners, but could be easily adapted to use in a game. It also shows some simple artificial-shadow techniques (characters, objects and cargo-hold below deck), a realistic-looking skycube example, a background sound loop, even ship flags with cloth colliders. The cloth colliders would work, but the ship object's flags have all been grouped together as one object so the cloth-physics are messed up (each flag should be a separate object with a separate cloth component). PS, All objects on the ship (including pirate and camer) are 'Child' objects of the ship so they sway and move with the ship, and it is currently self-guiding so you can set up a 1st or 3rd person controller and walk around on the ship while it sails. You could also set up a particle emitter for 'ocean spray' at the front of the boat as it sails forward, just make the emitter use the ship's bSpeed (from boatSail.cs) and you can have 'ocean spray' that automatically (according to speed) grows as you speed up, shrinks if you slow down, and disappears if you stop.
I tried different methods of making a rippling water mesh to go with this, but I got the best results adapting a 'procedural landscape' project to make a water mesh. If anyone's interested, search (maybe github or Asset Store) for "Procedural Landscape Unity Project".
