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).
