slider

slider (x, y, bmapScale, bmapKnob, min, max, var);

hslider (x, y, length, bmapKnob, min, max, var);

vslider (x, y, length, bmapKnob, min, max, var);

Horizontal or vertical slider that can be dragged with the mouse for entering values into variables.

Parameter

x	X position within the panel
y	Y position within the panel
bmapScale	Bitmap or image file name for the slider scale; also determines the slider direction. If the height of the bitmap is greater than its width, it's a vertical slider, otherwise a horizontal slider.
length	Range of the slider in pixels.
bmapKnob	Bitmap or image file name for the slider knob.
min	Value at the left/upper end.
max	Value at the right/lower end.
var	Global var to be modified by the slider. If moved to the upper or left position, var is set to the min value, at the lower or right position it is set to the max value.

Remarks:

For changing the slider range at runtime, use a min and max range of 0..1, and multiply var with the desired maximum value. Alternatively, use pan_setslider.

Example:

hslider(10,10,40,slider_map,1,8,my_var); // shifts my_var from 1 to 8 over 40 pixels
