Description of the use of the huddraw set of script commands

------------------------------------------------------------

The huddraw script commands allow you to draw up to 256 different graphic icons on the player's hud.

The element to adjust with each command is specified by an index number in the range of 0 to 255.

They currently broadcast to all players, but that could be changed if the need arises.

Commands Summary

----------------

huddraw_shader

This sets the shader to use for a particular huddraw element.

huddraw_align

This sets the alignment of the huddraw element.

Valid values for horizontal alignment are "left", "center", and "right".

Valid values for vertical alignment are "top", "center", and "bottom".

huddraw_rect

This sets the position and size of the huddraw element. X and Y specify the position of

the upper left corner position. Higher values of X move it to the right, and higher

values of Y move it down. When you set the alignment, the XY position specified is

relative to that alignment. For example, if you align it to the right edge of the hud,

the X position should be less than zero so that it the upper left corner will be brough

back to the left onto the screen.

huddraw_virtualsize

This let's you set the huddraw element's size and position according to a virtual screen

resolution of 640x480. What this means is that it lets you treat the hud like it's always

at 640x480, and it will be properly resized and positioned according to the actual resolution.

huddraw_color

This set the color of the huddraw element. Each color channel should be between 0 and 1.

huddraw_alpha

This set the alpha of the huddraw element. It should be set between 0 and 1. This is also

used to turn off a huddraw element that is no longer wanted by setting the alpha to 0.

huddraw_string

This sets the huddraw element to display a string instead of a shader graphic. The size

of the font can not be adjusted, but the color and alpha settings do affect the text.

The width and height parameters of huddraw_rect are only used for alignment centering,

Not for setting the size of the string.

huddraw_font

This sets the font for a string displaying huddraw element to use. The names of available

font can be gotten from the game/main/fonts folder. The file names of the .ritualfont files

in there are the names used for the fonts.
