Pointing cannon with up and down button

Hello to all.
* Who can advise me how to create a cannon that raises and lowers the cane with 2 keys up and down,
I do not understand where to start creating this effect
The cannon must have a fixed end as a pin. and change degrees with 2 keys

Sorry my translation; D

you can simply change the cane angle,
make sure you set the hotspot in the middle of the "attached" body section of the cane,
this will be the pivot point your cannon will rotate on,
then you can do:

repeat while player moves up
>>> set cannon "angle" to cannon angle +/- (amount to rotate, i.e. 0.2)

repeat while player moves down
>>> set cannon "angle" to cannon angle +/- (amount to rotate, i.e. 0.2)

where to put + or - depend on the cannon orientation, and your specific needs

then you might have additional requirements, in case let us know

(and welcome! :))

Hi I am a real beginner,
but how do I create the point where it will turn the cannon, sorry I have to create an active object?

sorry,
yes I was talking about an active object, it's the most flexible object you will use 99% of the time in Fusion,
the basic building block of your applications

here's a very quick example of what I was suggesting above:

Attachment 23782

doubleclick on the object in the frame editor,
you'll see the "hot spot" is in the middle of the green diamond,
that's the point X,Y coordinates of an object are taken upon,
and the pivot point around which the object will be turned when changing its "angle"

Thank you,
thanks to your advice.
* if I can still ask for help.
now I would like to get a cannon ball out of a point in the direction of another point.
Let me explain better, clicking on a cannon I would like to create an active object (cannon ball) that goes in the direction that may vary according to the inclination of the cannon
I'm trying with poor results ..

You'll see you always have a number of different choices to make the same thing,
the only problem with this is default solutions are a bit more heading towards "directions" instead of "angles",
so to get a smooth result you'll have to code in some math, or use "physics" movements, which support angled movement.

So, basically, upon clicking on cannon, you'd "create" a cannonball originating at 0,0 from cannon "ACTION POINT"
(cleverly suspecting the cannon would have to shoot X), I've already placed the action point in the mouth of the cane)
then, you need to move the ball in the correct direction,
so for examlpe you can use "physics bouncing ball", set initial speed to 0,
and then in the same "create ball" event, in "movement - physics movement"
set the ball "impulse" >> force to (any number) and angle to cane angle

if you want the math solution or other ideas drop a line

this is what after hours of work, without knowledge and your help I managed to do. the cannon rotates up and down with the arrows.
the cannonball starts at point x but I see that moving the cannon does not stay on the tip of the cane, but giving direction to the ball with the arrows I can not.
Try using your advice
Thank you so much,
Daniel

I made some slight modifications (setting the ball impulse and angle, changing the cane hotspot etc.)

Attachment 23789

this should fix the issues you were experimenting?

Thank you very much, you are really kind
* 1 question, but where am I? a full written guide with all the features of the MMF
* Now I want to create an active object after 4 seconds that an object hits another object.
But I would like to know if, apart from the examples in the tutorial. is there a complete guide?

There's a lot of guides and tutorials (both text and videos) out there,
I'm unaware of a "complete guide" (which would be quite impressive given how many things you can do with Fusion! :))
there are some books you can check out, you'd have to search for them though,
and there are online wikis (clickwiki and the library)
there's the "help" funciton inside Fusion itself, explaining most of its functions
this forum is a very very large source of informations (sometimes "googling" for answers gives better results than the search function you find up there)
and there's the Technical Manual collected by Nivram:
https://www.castles-of-britain.com/mmfexamples-misc.htm
and more and more,
perhaps some other forum member can add other detail on this

Your latest request is doable with "timer" events, try to experiment and you'll likely get to a solution
(if not, no worries and come back here ;))
