I just downloaded S2 W from scratch. Everything seems to work fine except when i press my mouse button to accelerate the cars do not move . The steering wheel moves and the engine roars but not the car. Under "options" under "controls" at the top it says "no controllers detected". I am at a loss as to how to fix this. Any help would be appreciated. Thank You.

I don't know if you have made a typo, but the latest version is X not W and it is multiplayer incompatible with W. Just in case you are wondering where all the racers went

About the mouse problem, have you clicked on the "mouse/kb" button in Options>Controls (top left) to tell LFS you are driving with the mouse and not with a wheel?

In the same page there are the button assignements.
Make sure you have assigned the "accelerate" function to the key/button you want.

Your problem may be as simple as mine was. I even hesitate to call it a problem, because it was stupidity on my part.

The first time I tried to race, the green fell, I revved the engine and sat in dismay as the other cars rudely left without me. I just sat there gunning the throttle thinking the damn crew must have forgotten to attach the driveshaft. Then I realized, maybe the tranny is in neutral. Bingo!!!

Made a reminder to myself: This is a sim. Just because you selected auto trans doesn't mean you'll automatically leap from the start line as you can in your Xbox and PS2 titles.

Thank you for your reply. The problem you describe sounds like mine. However, i have no idea how to select autotrans or anything to do with the transmission. I'm on single player if that makes a difference. Version X ( that was a typo). Thanks.

Select Options, then Controls. Find the line "Gear Shift Mode". Click on Auto or whatever you like. Keep looking down through that same column and you'll see that the s key upshifts, and x downshifts. When using a mouse, I realized I had to tap s at the start to put it into 1st gear. I imagine you can do that before the green, but use the brake or handbrake to hold the car to avoid a false start. The controls can be mapped any way you like whether using a mouse/keyboard, or wheel.

I hope your problem is as simple as this.

Thank you very much for your suggestion. It solved the problem. It's funny i never had to press the S key to get in gear with the older versions of the game but never the less it works. Thank You once again.

Sure. You're welcome. Glad that's all it was. If you think about it, it does make sense that if you are going for a true sim experience, it should be up to the driver to put the car in gear. Wonder at what point along the development timeline it was added in?
