Dialog boxes and Launching

[JuhaJGamer]

So, I've got a bit of a problem. 1: I haven't coded since like 0.90, and 2: I need to get myself a dialog box BEFORE the loading screen on launches. That is, execute a function when the "Launch" button is pressed in either the editor or the ksc screens, preventing the loading until the function returns and/or is resolved in another way. For example, the recovery warning when trying to launch with a vessel on pad does this. I merely ask for two things: Is it possible, and if, how. And of course I have the alternative of using onVesselRollout or something, but I really want to do it before the loading screen. Before attacking me for this, I have spent the last hour trying to figure it out. Sorry for the possibly stupid question, just looking for help, and thanks in advance! For context I'm using a ScenarioModule with the [KSPScenario] attribute.

Look at Kerbal Construction Time, also KRASH,mthey both intercept the launch key

Thanks, will look into it. Stupid that there doesn't seem to be an obvious way to do it, since so many nearly useless events have an obvious way to intercept them. Then again, the launch function was probably one of the first implemented, ever.

If you really must, you could try using Harmony to patch a prefix or postfix onto the click handler for the launch button(s) or somewhere else relevant to intercept a launch and do your stuff before allowing rest of the program flow to resume.

I've had success with using this approach as a workaround for events that I am interested in but don't have any corresponding entry in GameEvents.

I don't recommend this.  There is a way to do it, the mods I mentioned already use it, as well as (I believe) EPL, and maybe some others.
