movement X and Y coords

sangano

Hi,I'm trying to move a sprite in a 3d scene only in the X and Y coords with the mouse but doesn't work as I need. I want this because the sprite is a target icon to shoot.Someone did something like this.Thanks!

And what [i]exactly[/i] doesn't work right?Does the movement along X work the way you would expect? might it be that instead of the Y axis you intend to actually use the Z axis, perhaps?

It would be good to get some more information.If you want to do a 3d shooter like game where the character is static and just can set the target cursor you would use camera rotation. (which is controlled by the mouse) So that the cursor/target is always in the center.If you try to make sth. like a top down building game (rts style) you would use a ray casting from the camera trough the mouse cursor to a plane, calculation the intersection point and use that value for the position of the cursor/point you would like to build sth.

What I'm trying to do is a character(in a 3rd person view) moving in the X axis and the target move freely according to the mouse position only in X and Y axis.What I did is mostly like you said toger5 [quote] ray casting from the camera trough the mouse cursor to a plane, calculation the intersection point and use that value for the position of the cursor/point[/quote]But the problem with this is all the axis moves. So, sometimes the target looks pretty near or far from the camera view. This happen when the mouse is close to the side of the view

So if you change the cursor to a image, the click happens on the top left corner (0,0) of the image.I had this problem in one of my games, you can see how I solved it here: https://itch.io/jam/godotjam032016/rate/59460The just have a look at the scene "pointer.scn"Hope that helps.
