panel.alpha

panel.alpha

Determines the transparency of a transparent panel. At 0 the panel is totally transparent, at 100 it is totally intransparent. Panel elements like buttons inherit the alpha value from the panel. This way panels, buttons etc. can smoothly be faded in and out.

Range:

0 .. 100 (default: 50)

Type:

var

Remarks:

For panel transparency, the TRANSLUCENT flag must be set or an alpha channel image ( TGA 32 bit, or DDS) must be used.
Alpha channel images (TGA, DDS) are displayed at their normal transparency with the default alpha value of 50. To make them 'more transparent', use alpha values below 50. Values higher than 50 have no influence on alpha channel images.

Example:

my_panel.transparent = ON;
my_panel.alpha = 0; // Panel 100% transparent
while (my_panel.alpha < 100)
{
  my_panel.alpha += 20*time_step; 
  wait(1);
}
my_panel.transparent = OFF;
