Some of you may know that "The Official Book of King's Quest" included three small fragments of AGI code for ROOM 7 in the AGI version of KQ4. These fragments are given below along with the same fragments taken from the game itself. There are a few differences which is to be expected but generally the code is very similar. These examples show how the coder wrote the code and what it now looks like in the final product. I've included a few comments where some interesting observations can be seen.
FROM THE BOOK
animate.obj( smoke); ignore.horizon( smoke); set.view( smoke, v.fish.cabin); set.loop( smoke, 1); ignore.blocks( smoke); position( smoke, 95, 16); work = 3; step.time( smoke, work); cycle.time( smoke, work); draw( smoke);
FROM THE GAME
animate.obj(7); ignore.horizon(7); set.view(7, 114); set.loop(7, 1); ignore.objs(7); [ These two lines have been added. set.priority(7, 5); [ ignore.blocks(7); position(7, 95, 16); assignn(152, 3); [ Equivalent to 'work = 3;' step.time(7, 152); cycle.time(7, 152); draw(7);
