This volume is about methods in game research. In game research, wide variety of methods and research approaches are used. In many cases, researchers apply the method set from another discipline to study games or play because game research as discipline is not yet established as its own discipline and the researchers have been schooled in that other discipline. Although this may, in many cases, produce valuable research, we believe that game research qualifies as a research field in its own right. As such, it would benefit game researchers to have collections of relevant research methods described and developed specifically for this type of research. Two direct benefits of this would be to illustrate the variety of methods that are possible to apply in game research and to mitigate some of the problems; each new researchers has to reinvent how methods from other fields can or need to be adjusted to work for game research.
In addition to door, I want to have force field gates that are controlled by levers. I also want to have force field gate malfunctioning so that the force field goes on and off defined intervals (with random variation).
Next I setup something for regaining energy and health. I want the PC to be gain health or power while it stands next to the power-up (and as long as the power-up have something to left to give). The power-up keep its state so that it does not pop us as full if the PC gets back to the level. I also want to visualise in some degree how much health/energy power-up has left or if it is fully drained.
This part adds logic for the PC and keep track of things such as health, dying. I also add functionality for invisibility (that have already partly added in Guard class). I also add HUD using the new GUI system to show health and energy (that is used to maintain invisibility).
Now we have a simple agent that follows patrol route and change colour when it sees the player object. To make this usable and interesting in the game, we need to extend to functionality and have something else than a cube.
