| - | OK, that's 3 of 4. The last one is easy to make but can be tricky to configure. So far we have created axises that makes an object rotate around it. All the stuff we have made so far are for either doors that swing open, a switch that flips and a spinning radar structure. All those are rotating objects in one way or the other.

| Well, the truth is that you cant. OFP does only rotations, its a silly engine limit. But we can fake it to some degree. What if we place the axis faaaaaaaarrrr away from the actual door structure. And let it rotate only a small degree? Done right, and given that the door structure isn't too big, it might just look like the door slides linearly without rotating!

| - | This is the main trick used to create sliding doors in ofp and it works quite well in most cases. Problem is that the larger the door is (say a hangar door), the more movement is needed to open the door (larger angle) and the more apparent the rotating effect will be. A trick would be to split the door into smaller doors and have them rotate separately, but it can be tricky to pull off. | + | This is the main trick used to create sliding doors in ofp and it works quite well in most cases.

| - | For out sliding door, which is quite small, we wont have much problem. Figuring out a good location for the axis AND tuning the right rotation angle (more on that in the configfile in the end) is the main problem getting this trick to work.

| - | You gotta watch out for some issues when making an axis. If any of the doors seems to rotate the OPPOSITE direction then you compile the addon (don't do that yet, still some more stuff do to), then you gotta go back in o2 and //reverse// the axis, either by selecting it and hitting W or by swapping the vertice positions of an axis.

| If you study it, you will notice that the radar dome animation settings seem pretty odd. And they sure are! They seem to have an very large angle1 (60000+ in radians) and the animPeriod is set to 100.000. Well, the truth is that ofp didn't support constant rotating animations (except for some hard coded ones like the ship class` radar) and with normal settings and a angle1 set at 2*3.14159 (360*), it would just rotate one cycle and then stop. But thanks to some pioneers on the forums, they found a way to break this limit and create a constant spinning animation. Basically by setting the angle1 AND animPeriod to very high, you will force the radar to rotate slowly around the axis multiple times. It wont be forever, but with such a high angle (60.000 radians is A LOT of degrees!) and the time set to 100000 it will most certainly run for hours before it stops, and most people wont ever see it finally stopping. | If you study it, you will notice that the radar dome animation settings seem pretty odd.
