Checking if mouseY is moving

[AggrorJorn]

I'm looking for a way to see wether I'm moving my mouse in the Y direction (forward and backward).

if MouseDown(1)==1 then
		if MouseY = "Y moving forward" then
			do stuff
		if MouseY = "Y moving backwards" then
			do stuff
           end

 

Any suggestions?

Look at any of the example games, like fpscontroller.lua. Usually they reset the mouse position to the center of the screen at the end of every Update. Then inside the update you can compare the current mouse position against the center position to see how much the mouse moved in any direction that frame.

I wouldn't advise setting the mouse to the center of the screen however. I run duel monitors and I found that on one monitor GraphicsWidth()/2 gave a number with a decimal which screwed stuff up. Normally when in game mode (outside the editor) you don't run into this but for some reason inside the editor it's not always correct. The thing I realized last night is it doesn't really matter what you set the mouse position to as long as it's consistent. So I just set it to 200. If you don't require the mouse to be shown, you MoveMouse(200, 200) at startup once, then in your Update() you would first check mouse x & y minus 200 to get the difference in position, then MoveMouse(200, 200) to reset it. This will give you the difference that the person moved the mouse from the location 200,200. If it's positive or negative will tell you which way they moved it.

Now that I have a direction I can look into I can start puzzeling. I've created this sofar:

 

before main loop:

currentY = MouseY()

main loop:

centerY=(GraphicsHeight()/2)
		if (centerY >= currentY) then 
			texty = 1
		elseif (centerY <= currentY) then 
			texty = 2
		else
			texty = 0			end

 

after the update:

fw:Update()

--get the current Mouse Y position	
currentY = MouseY()
