i am trying to program a simple game using opengl/glut under linux, and i
have a few questions...
the idea is to make a good version of the mediocre warhammer 40k games
that have been produced. i am thinking of something that has myth-like
graphics, but turn based.
i am using an nxn array corresponding to a level map (where each entry is
a height value) where i could potentially sub-sample the height map to
get a terrain of triangles (or a bez-mesh if i'm feeling masochistic)...
so my question is this. if i wanted to tell a particular "troop" on the
level map to go to another position on the level map, how do i correspond
the mouse click to a position on the potentially translated and rotated
level map? i know there is this concept of selection in opengl, is this
the way to go? is this fast enough not to be too cumbersome? or should
i do the level map in a completely other way to accomidate for this type
of play better (i.e., don't use an nxn array level map, but something
if i do use an nxn level map, and i choose not to use the opengl
selection features, does anyone know of a good way to find the
corresponding position of the mouse click on the level map that doesn't
take order n time?
