Mortar Interface

When you click on the mortar, you'll bring up 12 stages with the following options. Stage 0 is launched from the mortar; stages 1-11 are launched from another stage which you specify.

• Launch From

The parent of the current stage. Not available for the first stage.

• Flight Time

How long this stage will live. Range: 0.1 to 99.9 seconds

• Rockets

The number of rockets to use per repetition. Used for rings, fans, omnis and random. Range: 1 to 4000

• Direction

The direction that the rocket is launched from the parent: Forward, Backward, Pitch Up, Pitch Down, Yaw Right, Yaw Left, Ring, Fan, Omni, Random.

• Launch Speed

The speed of the rocket when it is first launched from its parent stage. Range: 0 to 6500 ft/sec

• Launch Roll

Rotates the rocket around its forward axis. This is a one time rotation at the moment of launch and not a rotation over time. Range: -360 to 360 degrees

• Thrust Forward

The acceleration on the rocket in the forward direction. Range: -300 to 300 ft/sec^2 (Note: Negative thrust can give you some strange and fun results as the speed reaches 0 and the rocket then endlessly flips over).

• Thrust Pitch Up

The acceleration on the rocket in the vertical (z-axis) direction relative to the orientation of the rocket. Range: -300 to 300 ft/sec^2

• Thrust Yaw Right

The acceleration on the rocket horizontal (left-right or y-axis) direction relative to the orientation of the rocket. Range: -300 to 300 ft/sec^2

• Launch Reps

Launch another set of rockets every N seconds, where N is total time of the parent stage divided by the number of repetitions. Range: 1 to 250

• Launch Offset

The delay after the parent's launch before this stage is launched. Effectively reduces the total time for repetitions mentioned above by the value specified here. Range: 0.0 to 99.9 seconds

• Star

The type of star to use. Only lists stars that you currently have in your inventory. You must select a star type to launch or test. See Star Recipes for available types.

Notes

1. Egypt appears to have a gravitational acceleration of -33.00 ft/sec^2.
2. The initial stage appears to last 0.1 second longer than the entered time. If stage 0 is a forward launch, you can simply reduce the Flight Time to get calculated values to work (example: 0.9 sec flight time with a 33 ft/sec launch speed will give you a stationary platform for the next stage).
3. These directions are relative to both the rocket and sometimes the ground.

 Forward sends the child in the same direction as the parent. 
 Upward will generally send the rocket towards the ground, except when the parent is going nearly straight up or straight down. For a straight up/down   rocket you'll want to experiment (my tests tend to say it was the last forward direction, for stage 1 that is north). To satisfy the nearly straight up condition, 5 degrees is close enough, 9 degrees is not. 
Downward is opposite of up (so generally towards the sky). 
Left (has not been verified - but currently I believe this to be the direction of your left if the top of your head is pointing in the forward direction and your facing the up direction). 
Right is opposite of left. 
Ring - rockets fly away from the center in a ring in the same plane as the up/down/left/right directions. A ring with 2 rockets is that same as having 2 separate stages launching each of left/right. 4 rockets from 4 separate stages launching each up/down/left/right, don't seem to act the same as a ring with 4 rockets. 
Omni - the child rockets shoot away in a sphere. 
Random - each child is fired at a randomly chosen direction away from the parent.
