APPENDIX D: 2D COCKPIT ADDED

FEATURES

RENDERED NEEDLES

Gauge Needles can now be customized to suit individual aircraft cockpits. Example shown

below:

#733 DIAL

cyclebits = 0xffff;

numendpoints = 9;

points = -2.562 -3.002 -3.56 -4.032 -4.608 1.1 0.593 0.148 -0.506;

values = 0 5000 10000 15000 20000 25000 30000 35000 40000;

radius0 = 0;

radius1 = 70;

radius2 = 14;

color0 = 0xff000000;

color1 = 0xff000ec5;

color2 = 0xff0c0c7a;

renderneedle = 1;

srcloc = 2839 2728 2987 2878;;

destloc = 252 1113 399 1260;

callbackslot = 120;

¿ renderneedle =1; is the new entry that will allow a texture to be rendered. Simply use

the source location of the texture in correlation with the destination location. Make sure

that both source and destination locations are the same size, i.e., 147 pixels by 147

pixels, or whatever the case may be. The base (center of rotation) of the needle/texture

also needs to be in the center of the source location box you define. If you have

overlapping needles (textures rather), the order in which they appear in the .dat file is

the order in which they are rendered. So for example if you wanted two texture needles

to be rendered on top of each other, the one you want to be on top of the other needs to

be listed second in the .dat file. Lastly, the textures need to be sized to the size of the

gauge. You can have higher resolution source graphics, but the “word” is down-sizing

them to fit in the destination location does not look as good.

¿ A small change was made to so that the fuel quantity needles will show the proper

amount of fuel in each of the two fuel tank systems (Forward-Right and Aft Left) when
