camera always moving down issue

[Rick]

When I print out my AND I press the left mouse BUT I don't move the mouse at all, WHY WOULD my RETURN 0.5? mx returns 0 like I would expect but because my is return 0.5 the camera always moves to the bottom.

 

if MouseHit(1) == 1 then
				mouseX = MouseX()
				mouseY = MouseY()
				MoveMouse(GraphicsWidth() / 2, GraphicsHeight() / 2)

				HideMouse()
			end

			if MouseDown(1) == 1 then
				mx = MouseX() - GraphicsWidth()/2
				my = MouseY() - GraphicsHeight()/2
				MoveMouse(GraphicsWidth()/2, GraphicsHeight()/2)

				camRotationY = camRotationY - mx / 4.0
				camRotationX = camRotationX + my / 4.0

				if camRotationX > 25 then
					camRotationX = 25
				end
				if camRotationX < -55 then
					camRotationX = -55
				end

				Print("MouseX = "..mx.." camRotationX = "..camRotationX)
				Print("MouseY = "..my.." camRotationY = "..camRotationY)
				leftMouseDown = true

				RotateEntity(entity.playerPivot, Vec3(camRotationX, camRotationY, 0), 1)
			elseif MouseDown(1) ~= 1 and leftMouseDown == true then
				MoveMouse(mouseX, mouseY)
				ShowMouse()
				leftMouseDown = false
			end

Oh I see. GraphicsWidth()/2 has a .5 but MouseX() seems to return an integer only even if I do a MoveMouse(GraphcisWidth()/2). Guess I just need to drop the decimal.

Isn't it in pixels? Can the mouse move fractional pixels?

[Rick]

I had to make a simple round() method since GraphicsWidth()/2 was returning a decimal number. It seems ok now.

Logically, a mouse cannot stand inbetween pixels.

I think you get smoother movement if you divide by 2.0 instead of 2. Round() usually tends to round down when it should round up, so you might get irregular movements.

Logically, a mouse cannot stand inbetween pixels.

Actually the mouse itself can have like 1000 units per pixel, which you can test by applying a small force to the mouse, and after a while the mouse cursor will move one pixel on the screen.

[L B]

It can move between pixels, however it cannot stand between them. But we both understand this.

Actually how can I handle this in the editor? I have 2 monitors and even though they both have the same resolution, the camera is fine on one, and starts moving down automatically on the other. I have no doubt this would work fine outside the editor because I can control the graphics width and height to be a whole number when divided by 2, but in the editor it seems to cause issues.
