Hi
i have make an animated  landing gear on gmax but in the game nothing move  ???

i have tag my 2 tire whit succes (hall wheell turn)
i have tag the left main wood stud of the gear  l_gear

the right main wood stud of the gear r_gear i have no

and attach l_tire to l_gear and r_tire to r_gear (as parent)

i have no chuck
and i have no retractable tail gear

i have made an animation at 50% the gear apear on c.o.f but whenne i press G key nothing move  ???

i have try 100% animation the gear have change position but nothing move again  ???

pls help i need a ejectable landing gear 

my plane but nothing

How to make a simply gear give me an exemple 

im newbye at gmax and never made an animation so give me an exemple of a simply gear whit 1 tire and 1 gear how to animate tag it etc etc ... ??? thank !

I been through these kind of problems before with Project Have Blue [F-117A Have Blue].

For the l_gear and r_gear to retract along with their child objects [or extend], do this:

Rename the l_gear to l_gear_top and the r_gear to r_gear_top. This is important for retract-extend animations. Then animate from retract-position to extend-position [0-100].

For compression-animations, use these tags: l_gear_bottom, r_gear_bottom. Use these tags on hidden boxes if you want the struts to bend on landings.

For rotating tires, use these tags only: l/r_tire_still, l/r_tire_blurred. I tried the l/r_tire_slow tag, but it gave me problems. For these tags, you don't need key-frames. Just simply adjust the rotating axis.

The reason I excluded the use of the "l/r_tire_slow" tag is that [in Project Mercedes] any tire with this tag tends to do some weird and unacceptable things. Trust me, it happened to me before. If this never happened to you, then good for you.

At this point, you should have landing gears that retract, extend, compress, decompress, and rotate.

For the tail-gears [or nose-gears], it all the same. The only difference is that you just need to use the prefix "c_*" instead of the "l_* or r_*" prefixes.

The tag issue was also true for the props that I make for any aircraft.

I hope this helps you because it worked for me. Good luck.

PS: I'll tell you the same d*mn thing that all the other people here in simviation have been telling me for up to 2 years. "Learn to get things done by yourself". I learned this lesson for Project Mercedes and Project Have Blue.

You need four markers.

First one goes at 0 or 1 - gear up

Second one goes at 100 - gear down

Third goes at 101 - gear down/no compression

Fourth goes at 200 - gear down/full compression

Why i must set the timer to 100-200 frame  i have no compression chuck just a gear to animate ?

i have try hall you said guys but nothing move on c.o.f  ???
it is possible for you guys to send me a gear working in a gmax file so i will be able to see what i do wrong ( erase hall the plane i need only  the gear ).

Not yet but i will check that soon thank for the pipe  8)

Got it ! 
i have find why the gear not moving 

have forget to put extenssion time in the contact point in the aircraft.cfg 

Thank guys !

now the thing move greyt !

i have put the pivot bellow the plane so the gear fall out of the plane

but now i need the gear to dessapear at the end of the sequence 

somebody know the trick to make the gear dessapear 

Thank for the pipe Felix  8)
i will try this tomorrow and tel you if it work thank again
