This tells the game that the AI's vision originates from it's head area. The first thing you see at the top is "Z offset" with a current value of 3.00. So now you're looking at this Vision Description box, wondering what it all means. It loads initially with all the default Thief 2 values for a standard guard. From now on, when you select "Properties" of that particular AI, you will find "Vision Description" in the AI > AI Core tree. If you had to escape and resize, then you'll need to go back and select Add> AI > Ai Core > Vision Description again. If you're using Dromed's 1024x768 mode, your desktop needs to be at least 1280x1024 to properly see the menu. If this is the case, you will have to resize your desktop. If the box is taller than your screen and you can't see the OK button at the bottom, you can press the Esc key to exit. A tall vertical box will appear, with many settings in it.

Then select AI > AI Core > Vision Description.

Click the ADD button on the box that pops up. With the AI selected, click on the "properties" box at the bottom of Dromed. Caveats aside, I'll delve into the heart of the matter.įirst, we need to know how to override the default vision parameters in Thief 2. Thus, for example, if you wanted to give the illusion that a guard is half-asleep and not really paying attention (by reducing his vision), the player will have no idea that the guard has reduced vision, and will be more likely to seek another way past him than to "test" his ability to see the player. It's important to note that the player will have no idea (at least at first) that a particular AI has something different about its vision. Modifying the basic vision parameters we can expand his FOV (Field of View) to encompass the street below. A simple example of this would be if you built a "lookout tower" for a bow guard, but he's so high off the ground that he doesn't notice anyone passing by below. That being said, there are times when it is desirable and beneficial to adjust the default vision. Over-customization of AI's vision will most likely negatively impact gameplay, not to mention causing you, the builder, lots of headaches and much time spent on testing. It is worthy to note that in the vast majority of cases, the default vision parameters are just fine. Here I will attempt to detail for you the basics of AI's vision parameters in Thief 2.
