Animations in TS? Very easy..
Errr...what exactly are you trying to do?
Flying ships and stuff can be done, people walking are more of a problem without plugins..
Take a closer look at the play and record tools...
You have a small window wher you set recording speed (PAL, NCTS, etc... the one with 24 frames per second is the best...). Don't select the scene, select object in the checkbox, then set the animation length to let's say 50 frames, click record and move the ship arund. then set it to 100 and move it aaround again (the smaller the intervals the better - note this is done so becoause TS moves the ship from the beginning position to the ending one during those 50 frames - and it does that using the shortest path, so devide it's path is smaller ones)
once you're done with onew ship, return the frames to 0 and repeat it with another ship.
When all ships are set to 0, just select the scene in the checkbox and hit play...watch the fun...
