This is a basic 2.5 stage rocket based on the tutorial. It fires side boosters first, then center booster, then the final payload stage.
The Vizzy program waits for a target to be selected, and the "Launch" activation group to be enabled, and then calculates the idea launch timing to achieve a rendezvous with the target.
This program assumes that the target is in 150 km orbit, and it has been tailored for this craft using some parameters set at the beginning of the program. These include 1) the time it takes this rocket to achieve its 150km circular orbit, 2) the number of degrees this rocket will travel around the planet during launch, 3) an error correction, which is a number of degrees added to the offset to the target. Unfortunately there is some issue with the math I use to calculate precisely when to launch, so I have to tweak the error correction based on experimental results (I launch the rocket, check the resulting distance from the target in degrees, and then adjust the error correction and relaunch).
Note the payload in this rocket is not ideal, it was just thrown together to test the rendezvous. It is a little light on monoprop, so you may need to use the rocket engine to get close before docking maneuvers.

it got at -2.4 km , i did something like that in the early vizzy, but mostly based on trial and error with a dedicated radar that uses pitch intensity value to lock azimuth and alt for targets. Check my LRD craft (Launch, Rendezvous and Dock) , it's primitive script, you can use the "dock" section , it can work for up to 15 Km range using RCS (the craft was basically a mono-propellant tank lol)
