I'm making a level editor in a 3D environment and I'm having trouble with the tool.

You use the mouse to move a tool across your level and it works fine when camera angle y() is set to 0. But if I move the camera to a different angle, the tool still moves like it did when the camera angle was set to 0

In other words, if I moved the camera round to an angle of 90 (y axis) and I moved the tool upwards with the mouse, the tool appears to move left on screen. Its so annoying!

Can someone please tell me how to change this?

The simple way is to create a hidden object, orient it to the same direction as the camera, and move it with the mouse. Your tool should then be coded to follow the hidden object.

You could also consider using EzRotate, and the tutorial I wrote to do exactly what you are doing...

Thanks!

Is that tutorial for DarkBASIC professional? or the original? Because I'm using the original one. And I dont understand DLL's!

What I did in MatEdit was pre-calculate the movement parameters in two arrays (one for X movement and the other for Z), for all 360 degrees the camera can be rotated.

When you move the object in question, you simply use ObjMoveX(Camera Angle Y()) and ObjMoveZ(Camera Angle Y()) to move it.
