Construction help!

So i’m having a few problems with making a few things that shouldn’t be too complicated. I’m quite nooby but please bear with me.

  1. In my constant attempt to make a cannon, i don’t seem to have enough force pushing my desired object out. So i need a “supercharged” forcer

I used a wire-forcer and hooked it up to a button, and i’d have to spam the button for said object to come out. (Even when it does come out it has little to no distance).

  1. An explosive that explodes-on-impact. I made a catapult and i don’t like igniting barrels and watching them explode in midair. And with PHX explosives, they never explode on impact. I’d also like the same result with a missile for example so i can thruster it and it goes boom.
    (and something to use for #1 as well)

Thank you for your time =)

I had some issues with the dual input in Wiremod before understanding the thing completely. (I guess you’re using dual input?) Make sure the “Value 1 on” is at ‘1’, the “value off” is at ‘0’, and the “Value 2” is on ‘-1’.

Of course, this only works for some stuff, but hopefully it’ll work with your forcers!

I have no clue what duel imput is and how to modify D:
Pardon my noobyness
