Default impuls will not stop..?

Hi

I have an animation of a small rocket, it's suposed to shoot of and later loose its power and fall to the ground.

I'm doing it by setting impuls y to 5000. That's great it shoots of.

later I set the impuls y to 0, and it should fall down, right? Anyway it doesn't - any idea what could be wrong?


If you like you can see the file here: http://www.contentdepot.dk/exp/rocket.zip

Sounds like you need a gravity field.

I know I have one, but I can't find it.. : )

How can I see my settings in the gravity? Is gravity global or attached to certain objects?

If you open your Outliner, it gives you a list of all the objects in your scene. You can select it from there if you have one.

Gravity is not global. It is applied to whichever objects you have selected at the time of creating it.

If you created it without telling it to affect anything, you can do so under Window > Relationship Editors > Dynamic Relationships.

In this window, on the left, you see your Outliner list, on the right is the list of any sort major dynamics object depending on what selection mode you have at the top of the right side.

With fields selected, you see your fields. Select the objects you want the fields to affect on the left, then simply click the field on the right, turning it a yellow color indicating it is active on the selected object.

the gravity is there allright.
Magniyude 25 - direction y -1

Can it have something to do with max distance -1?

you may need to increase your magnitude. Are you certain that the gravity is affecting your object?

Window > Relationship Editors > Dynamic Relationships.
and I choose the rocket model. The gravity shows up. so yes it does, but it doesn't have any affect.

I've set the impuls y to 0 and active to on for the hole animation. So ofcourse the rocket doesn't shoot of. But if the gravity thing works, shouldn't it fall to the ground?

Got it working, thanks for all the help.

The problem was the impuls y it was to strong so, it just went of.

One last thing: Is there a way to see only the keyframes for one selected channel? Now I can always see the keyframes for all the channels.
