Godot get object position 3d

Hi all. First, I can not explain myself well in english or spanish and second, I come from unity engine Here is the script. The problem is that the position of the building is very high something like ,1,20What I try to do is that the building moves in the position of the cursor and follow it, in unity I solved it using raycast, but in godot I do not understand how it works.

Good is almost ready, I have problems with height, for example elevated ground use tiles but it works. Now if you want the building to follow the mouse in 3D The hit variable is a Dictionary. Gracias, No se me habia ocurrido de esa forma, vere si funciona Thanks, I did not think of it that way, I'll see if it works. Maybe I'm just too sleep deprived or missing something, but nothing in this answer seems to address the question of how to move the object, as in following the mouse.

Indeed, because it depends how you want the object to move. In 3D you can mostly move objects along a surface or a plane, so for example if you have a terrain on which your objects are, you would use raycasts as described in my answer to get the hit position on the terrain eventually using a mask to not pick other objects and translate the object to that position as you drag the mouse.

But it's just one way amonst others. Resolved Move a 3D object with the mouse pos. Please log in or register to add a comment.

At first it does not seem very intuitive how you can spawn objects in godot. However hopefully in this tutorial I can cover everything you need to know about godot spawners, everything from how to spawn a player, the godot lifecycle, using timers and how to set the position of the spawn or even randomly spawning objects in random positions.

Also looking at how to use godot to spawn a bullet. Godot spawning of enemies will also be covered. There will be a tutorial video under each section of this blog post if you are interested in watching the video format instead.

To spawn a player in godot we need to just start by setting up a player scene which we can use. For this I am going to use the basic player icon. So for simplicity sake I have given my player a KinematicBody2D and CollisionShape2d for when we expand our project further. So you can just replicate what I have below. Once you have that save your player as Player.

Now we going to create a new scene called Game. Which at this point will only have a Node2D which I renamed to Game. Once done we can now add a script for spawning our player, but first before we do that hit play to just check that the screen is showing blank and that the game.

You should have something like above. Ok so now on the FileSystem right click and create new script. Call it PlayerSpawner.

Great so now we have a player spawning. Let us create a way for our player to shoot a bullet. To spawn a bullet we first need a bullet. I created a very basic rectangle image which we will use for our bullet.

To get this working we are going to start off with a new scene where we can create a bullet sprite and some bodies to allow us to shoot our bullet at a velocity. So go ahead an create a new scene and save it as Projectile.

You will want to replicate this node structure to make it work.The reason for this small tutorial is to clear up many common mistakes about input coordinates, obtaining mouse position and screen resolution, etc. However, it does not make as much sense outside of that scope.

Godot uses viewports to display content, and viewports can be scaled by several options see Multiple resolutions tutorial. Use, then, the functions in nodes to obtain the mouse coordinates and viewport size, for example:. When the mouse mode is set to Input. Use event. How much does it cost? What are the license terms?

The first real problem I've run into is getting a character's arm to point at the cursor. After searching online this is the code I tried to use:.

It almost works.

Here's what I'm trying to do:. What I'm getting is off by about 45 degrees, and stretches the image out in a weird way:. Any assistance would be great. For the offset, the only thing I can think of is maybe the position of the plane is the problem? Maybe set the distance to the Z axis of the origin of the global transform of the node, so the plane's depth is at the same distance as the character?

Another thing that could, potentially, be causing the problem is the length of the raycast. Maybe it is not long enough to hit the plane, so the cursor3d variable's X and Y coordinates are zero. I do not think this is the issue, but it might be something to look into.

You want to use the Player nodes translate. Also I think you might need to normalize the Cursor3D vector. This makes a lot of sense. I readjusted the code a little bit and it's no longer stretching, but huge. And thanks for welcoming me!

Megalomaniak said: cursor3D. The character moves along the X, so to keep things on the same depth, I need to keep the Z the same right? And forgive my newbie ignorance. I've done some game design and coding in the past, but 'normalizing' is a new concept to me. How would I implement that?I want to detect the 3d position on a MeshInstance where a click occurred, and the raytracing documentation is confusing me. I tried putting raycast.

The documentation is primarily referring to creating Raycasts through code, so the code needs some modifications to work with Raycast nodes. If the position is 0, 0, 0 then the Raycast probably didn't collide with anything, so it is returning the origin of the scene. The raycast will can only collide with physics body nodes with collision shapes by default, with options to allow for colliding with Area nodes with collision shapes.

Another issue could be that the origin of the raycast isn't being set correctly. If I recall, I think camera.

I have not tested the code, but the following should work, assuming there are physics bodies with collision shapes in the scene:.

Peter Boughton Posts: 5 Member. August in 3D. TwistedTwigleg Posts: 2, Admin. August You might need to replace event. Because we are using a Raycast node, we do not need to add the position of the Raycast node, as the ray's origin will automatically be the origin of the Raycast node.Godot engine is a 2d and 3d open source cross platform game engine.

As of now, Godot engine is 2. This post is targeted towards beginners who are coming to Godot engine from other engines. If you have no experience in any game development, you may get some help here but I recommend you to look at Godot wiki on vector maths and transformations. I believe you can apply these in advanced things like character movement, camera control etc. Vector A vector represents a magnitude and direction. In a game engine, a vector is used to represent a position or a direction.

Godot 2D Tutorial- How to Position, Scale, Rotate, and Move Objects using Script

Let us assume that there is a 3d world in Godot. The world is where we put all game objects and it is where the game runs. If we add the global right vector i. If you are coming from Unity, take note that Godot has a slight difference in the axes compared to Unity. The forward direction is not positive z, but it is negative z. Every object in the game world also has its own position and a direction. You only need to understand that every object has a transformation matrix which represents the position and its orientation also the scale, but leave it for now.

So if we know the transform of a game object, we can get its position and its direction. We get the position from its origin and orientation from its basis. By changing the origin of the transform, we can change the position of the object. Instead of using this code, godot provides a simpler method for doing this.

The above code just moves the gameobject on the world x axis. Even if we rotate the object, it just moves along the world x axis because the object is moved in global x axis. Global transform is independent of local position and rotation.

For that we need to know the local right direction vector of the object. We can do this by. The passed Vector3 delta,0,0 is converted to its local space internally. If we want to move to the forward direction, which is -z. Move to a position To move to a position, we need to get the direction vector from the object to the target position. We have a targetObject which is where we want the object to go.

So, we find the direction vector by subtracting the source from the destination position. We only need the normalized vector which just represents the direction. Rotation of an object Rotation is somewhat complex if we dig deep. In the editor, the rotation is represented in euler angles. It is super simple that each of the three angles represent the rotation in all angles. This is called Gimbal Lock. Quaternions are used to represent the orientation of a 3d object.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I am an amateur developer starting a simple third person 3D game in Godot 3. I also have a Camera as a child of the Player so the camera follows behind and rotates relative to the Player. However when the Camera rotates, pressing forward still moves the Player along the global z axis! I would imagine that when the player rotates and you press forward, the player should move away from the camera.

Is there a built in way to move along an x or z axis that is based on the rotation of the Player? Godot and most other 3D applications do not use what are called Euler Angles for rotations, which can be visualized by the rotation 3D gizmo in the editor for performance and technical reasons.

Instead, it uses Basis vector transformations. Instead, imagine you make a 2D object and give it 2 vectors that are 90 degrees apart and the same length; one on the x axis and one on the y axis. These are the object's "local" x and y coordinates. When rotating the object, instead of rotating the object itself, it changes the coordinates of the terminal points of the vectors in a way that keeps them 90 degrees apart and the same length causing its local x and y to "rotate". Sort of like if you make an 'L' with your hand, place it on the table, and rotate it back and forth.

The rotation is not stored in the angle of your handit is stored in the position of your fingertips. The same thing happens in 3D, but with a third vector added along the z axis.

Most importantly of all this however, is that you can refer to these vectors and use them by doing transform. To learn more about adding vectors and other vector maths, see this.
