Not exactly sure about the missile. I saw this somewhere. Might work.

For the missiles, set it's ignitionDelay to 0.1. As for the bombs, it's a bit complicated.

@griges thank you!

i tried, the sum(FireWeapons) is not rounded, its in decimals, i tried round,ceil.. not work. i dont know yet
but it was to count how many times you pressed FireWeapons
but for the 1 bomb, add

zeroOnDeactivate , false

on the hinge/rotator you use, so the fin keeps deployed ,not retracted back

for the first, if only 1 bomb,, and name boom 50

SelectedWeapons="boom 50"&FireWeapons=1?1:0

if more than 1 bombs,
make every bomb activation using sum(FireWeapons)=x with x is numbers of each bombs.
so

SelectedWeapons="boom 50"&FireWeapons=x?1:0

im not really sure about the selectedWeapon part, havent personally used it yet
the point is just, the hinge/rotator you use for the fin, activate only if you pressed FireWeapon & the bomb is selected,(so not activated if you fire another weapon)

try get answer from someone else better than me 😅
