Mouse object- mouse speed

Jonathan

Hi All,

PLaying with the mouse object, the cursor moves very slowly. Is this the limitiation of the hardware/software, or can I speed it up somehow?

Thanks!

the returned value from the mouse could be scaled to provide faster response

Graham,

Remember I'm a thickie. I tied adding to the return value, I get a blurred/shifting cursor, but it moves at the same speed. Any hints, in small words, of where/how to this scaling?

Thanks!

OBJ

mouse : "Mouse"

PUB start

...

x += mouse.delta_x << 1
y += mouse.delta_y << 1
...



This will speed up the mouse 2:1

Ken,

Great! Now, where exactly do I need to use your snip? I am using the "VGA_1280x1024_Tile_Driver_With_Cursor", and am trying to modify the demo file that came with it. Sorry I'm so thick.

I did get it to work, but the cursor now goes out of the bounds.

How about this?

x += mouse.delta_x << 1 #> lower_x_limit <# upper_x_limit
y += mouse.delta_y << 1 #> lower_y_limit <# upper_y_limit

your limits can be constants

I think the mouse object has functions to set bounds and scaling, but I'm not sure how they work.· My only experience with the mouse object is from playing around with the graphics object.
