this type of things i usually put under "how clever are you?" you have to build a state diagram for what you want to consider and check for overlapping areas and choose which you will give preference to, then build a small state machine into your icon object for your character--depending on how you are handling that it could be for your character itself, but then that is up to you and "how clever you are".
so if i have 4 different states i want to represent, then i have to make 4 different ways of updating the icon, that could be as simple as changing the intensity of the icon, or xor-ing a pattern for each state through the icon or maybe 4 different icons--that is up to you also.
So once you have the 4, arbitrary number i chose here, states that you want to represent, then you need to build a state machine, my chosen way to implement clearly defined states aka defining conditions. that would be done with a "case statement" or a series of "if then else statements", once again--how clever are you?
now comes the twist of things: do you want your defining condition to be mutually exclusive in their representation or do you perhaps want then to overlap? So you have 4 states, does that mean you have 4 different things to represent? State 0, 1, 2, 3 or does that mean that you want then to be able to simultaneously express--that would be a binary flag with 4 positions or a singe hex digit--0 through F? in the later case you need to have some "or operations" to express the changes that will undergo with the icon. so you could be something like on-line, male, has sound, has video... all combinations of those selections offer 16 different states--4 bits of a binary flag aka 1 hex digit.
the mechanics of what you do to make those representations is up to you--i tend to, in the case the the binary flag (simultaneous representations of states), to have separate and distinct operations that will uniquely modify the icon--the image portion of it--and then incorporate that into the game (pass it to your player character object).
so i've given you somethings to thinks about, the reason i call this "how clever are you" is that there are multiple ways of doing the same things--it depends on what you want and what you see. design has an artistic element that is merged with engineering and there is where "how clever are you" is born.
So--what do you want to do, and "how clever are you"?
Out on HF and heard nobody, but didn't call CQ? Nobody heard you either. 73 de N7GH
