Make helper stay relative to a position while moving

[SaltAddict]

Is there a way to make the helper stay relative to a position while it moves?

For example, my character creates a helper (that is binded to root) that creates a diagonal projectile helper, while my character is moving backwards. Is it possible to make the diagonal helper move backwards with the character, but at the same time, keep flying diagonally?

[altoiddealer]

So wait, does it change direction when the character walks backwards?

Or are you saying that it should continue flying forward... but the player's movement influences the X velocity?

I'm just not following your description here

You could do it a couple ways.
One would actually be the animation. Where it's always bound to 0,0. But in the animation it flies up & to the right. It'll look choppy.

I think the next way would be to do some sort of posadd. Maybe 2 helpers nested in each other but the root might be enough.

You could try using a bindtoroot or parent with math. Like figure out the distance vs time.
[State 0, BindToRoot]
type = BindToRoot
trigger1 = 1
time = 1
pos = Floor(time/7),Floor(time/7)

Something like that might work. I havent tested to see if that would run though.

The floor thing doesn't work, it just causes the projectile to move very slowly

Do you mean something like this?


If yes, you can try something like this:

Code Select Expand


[State 7000, Pos]
Type = PosSet
Trigger1 = 1
X = Root,Pos X + INITIAL_POS_X + (Time * VEL_X)
Y = Root,Pos Y - INITIAL_POS_Y - (Time * VEL_Y)

Just replace INITIAL_POS_X and INITIAL_POX_Y with the helper's initial position relative to the char and replace VEL_X and VEL_Y with the desired velocity

Exactly like that. But that code doesn't work. I tried:

Code Select Expand

[State 7000, Pos]
Type = PosSet
Trigger1 = 1
X = Parent,Pos X + 25 + (Time * 10)
Y = Parent,Pos Y - 25 - (Time * 10)

And it doesn't do anything. So then I tried:

Code Select Expand

[State 7000, Pos]
Type = PosSet
Trigger1 = 1
X = Root,Pos X + 25 + (Time * 10)
Y = Root,Pos Y - 25 - (Time * 10)

And it still doesn't do anything.

[Felkazz]

You need to remove the VelSet you have already done and let only the PosSet do the work.

[Jesuszilla]

Look in the code library for my dizzy star code.

Nope, still doesn't work. The projectile moves, but the bind doesn't work

Look in the code library for my dizzy star code.

Can't find it. Searched all pages of the code library and the code archive thread but I can't find it

[Felkazz]

Can you post your code? Maybe there is something interfering with it

Oh, thanks. Can't believe I missed that.

Here it is, sorry, it's a bit messy. 100019 is the actual projectile. 100017 creates the projectile.

So, i see nothing wrong with that code. It is basically a direct copy from Thunderberts. Therefore something else is going wrong. Lets confirm that the code itself is doing well... anything.

If the projectile is moving the posset MUST be working. Nevertheless.

Alter it so it binds in specific spots and test each time. Change it to 25,-25. Confirm it shows up. Change it to 50,-50, confirm it goes where you expect. If that is working then the posset isn't at fault.

Alternatively

[State BindToRoot]
type = bindtoroot
trigger1 = 1
pos = 25+(time*10), -25-(time*10)

Should do something similar. This also takes facing so you could potentially make the helper always face the same way as the root although that might look a tad weird if it's a genuine beam.

What I meant was, the posset DOES work, but the helper doesn't follow the player. It's the same thing with your code, the helper shows up in the correct position, with correct speed, but it doesn't follow the root or the parent.

[Felkazz]

That is really strange... It should work... If you want, upload your char and PM it to me so I can have a better look and see what is the problem with your helper ^^

[Cyanide]

How can it have correct speed and not follow the parent. You don't actually SET speed in 100019. There is no velset. How is the projectile moving if the bindtoroot isn't working AND there is no velset?

You have another state 100019 is my current opinion.

Nope, just checked, even used the "find" tool to make sure. There's only one state 100019.

[Cyanide]

So we return to the previous question. How is the projectile moving if there is no velset in that state? You don't have a velset. If the bind is NOT working the projectile should not move at all. If the projectile is moving then the bind is working somehow.

Do a simple helper creation in light punch. Make it do nothing other than the code we gave you. If that works it's something wrong with your state.

[Felkazz]

I looked at the char and found the problem ^^
The thing is, the helper that causes damage IS moving according to the char, but the TRAIL is not! The trail is static, it doesn't move at all, so, we need to make it follow the char!
As the "head" spawns multiple trails, I made the trail "follow" the head with the reverse speed of the "head". So, put this on state 100018 and it should work:

[State 100018, BindToParent]
Type = BindToParent
Trigger1 = 1
Pos = -Time * 10, Time * 10


[Odb718]

You could try using a bindtoroot or parent with math. Like figure out the distance vs time.
[State 0, BindToRoot]
type = BindToRoot
trigger1 = 1
time = 1
pos = Floor(time/7),Floor(time/7)

Something like that might work. I havent tested to see if that would run though.

Odb718 ftw lol.
But seriously, quoting because of the odd need for Floor(). When ever I do math like this, unless I know it's something like Velocity that I know that can go into fractions, I always use Floor() just out of habit. Root probably shouldnt be used for the "tail" if it's supposed to focus on the actions of a helper.
And do Floor(time * parent,vel x *-1) or something similar if you want the true reverse of the head.
