Recording Mouse Locations

[Ben Robinson]

if you're not trying to get a running picture of where the pointer is every 10 ms, you could also do something like this...

List1:
name your procedure.  add two columns, one 'x' and one 'y'.  set the weight so that it will run a few times.
once you see that the skeleton works, you can also add columns for 'map1' and 'map2', add all your various .bmp filenames.

put the following 5 items into your newly created procedure.

Inline1:
Mouse.ShowCursor False

Slide1: displays your map (a .bmp image file).

Inline2:
Mouse.SetCursorPos Display.XRes/2, .35 * Display.YRes  'this part you may want to randomize - it determines where onscreen the mouse cursor will first appear
Mouse.ShowCursor True

Slide2: displays the second map.  set Slide2's duration to infinite, add a mouse to the allowable input devices, and set it to terminate upon receipt of a mouse click.  also, under logging, check RT so you'll record the reaction time of their response.

Inline3:
Dim xPos As Integer
Dim yPos As Integer
Dim mouse1 As MouseResponseData	
Set mouse1 = CMouseResponseData(Slide2.InputMasks.Item(1).Responses(1))
xPos = mouse1.CursorX
yPos = mouse1.CursorY
c.SetAttribAtSource "x", xPos
c.SetAttribAtSource "y", yPos

make sense?
