![]() Takes a bit of practice to remember which functions default to world movement, and which ones do a conversion for you. This will rotate a vector that points in the global 'forward' direction by the transform's rotation, which should point in the same direction as transform.forward. Vector3 velocity transform.rotation Vector3.forward. ![]() So if the object is rotated 90 degrees to the right, you've applied a new direction thats 180 degrees to the right (I think thats how it works at least!). Alternatively, if you really like manually applying rotations to vectors, you can use this. If the unity function already does that middle part for you, and you input a local direction (a direction thats already been rotated) you are effectively doing that rotation twice. Then I can apply the new local version to the position of my object to move it forward locally += convertedVector Vector3 convertedVector = (worldForward) If my object is facing to the right, it will become (1,0,0), since moving it forward from its perspective means moving it right relative to everything else in the scene. Then I can rotate that vector to match the rotation of my object. I can roll my own Vector3 forward, just for fun Vector3 worldForward = new Vector3(0, 0, 1) Unity also has a command to rotate a world vector to match a given local object facing, and visa versa, so we can actually implement our own system to better understand. Vector3.forward is internally just shorthand for Vector3(0,0,1), as unity considers Z to be the forward/backward axis of the world. Transform.forward is local, but as the dude pointed out, some unity scripts automatically convert whatever you drop in to local, so inputting a local converts twice.

If (Input.GetButton("Fire1") & Time.time > nextFire) Start is called before the first frame update Here are the codes of the two classes: using System.Collections ![]() So I tried: bullet.position += Vector3.forward * speed Īnd saw it moves the bullet into the Z axis.īasically I'm asking is whether there's a sub-function of Vector3 I'm missing which moves an object according to the direction of its own axis? Still moves it up the screen regardless of how the bullet is rotated. I saw the original function controlling the bullet movement: bullet.position += Vector3.up * speed The axis is of an empty child object inside the ship object, so its own angles are always set to 0. The tutorial made a right-and-left control of the player ship, but I changed it to rotational control (which took a while because for some reason almost no script correctly confined the rotation to the boundaries I've set).Īfter scripting the rotation, I wanted the shots to move forward on the screen in the direction of the axis to which it is spawned. I've used a simple Unity tutorial to make a Space Invaders game, but I want to adapt it into a different game. If they are moving but in random directions it is because the object is rotated,if the object is rotated there qre 2 options, the first just change transform.right for Vector3.right (also test Vectoe3.forward since depends of how you set up your world) or a second solution is create an empty object with 0,0,0 posituin and rotation, make the player child of the new object and make only attach.
