How do I control the axis of an object?

currently, the emitter thing will only fire upwards. This is quite frustrating.

There are a few possible answers and I am not sure which is best.

Its best if emitter objects are build with "up" being the desired direction and then placed. See the GunBot example.

I haven't tried it but apparently you can make the group a component and then modify the axis to select the direction. Daniel might be able to tell you how.

Last, there is a special property to the Strength field in the emitter. It will take a vector in the form of 3 floats (X,Y and Z(up)) . Try putting these values in that field and note the results.

[0,0,20]
[0,20,0]
[0,20,20]

The first should cause the object to go up. The second to the side, and the 3rd one up AND to the side. The 20 is how hard to move in that direction.

Basically if you set the strength field to just 45 the actual result is [0,0,45]

I hope that isnt too confusing.

This is the most easy way to make it.
I attach a .skp example and a video to show you how you change the axes to a component.

just turn the object to point the way you want the emmitter to go, then go inside and change the inside static to be pointing the way it should, I't quick and simple
