I need to now how to use a specific calculation.
I want to do an action each 1,4,7,10th step etc.
Now i found out the formula for that would be "3n-2".
Thing is, i have no clue how to use that in Construct 2.
Is this possible to do?
you need a variable for your n.
So its 3*"variablename"-2
Then everytime the event runs add+1 to this variable.
(in fact thats exacly what you do in your mind with the sequences 3n-2 you add +1 to n on every run.)
I see, i never really had math and i kind of know nothing about it.
I see now that if you calculate 3*1-2 = 1, so indeed 3*2-2 = 4. These are indeed the numbers i am looking for!
I'm still a little bit stuck though.
When it comes to math all i get are brainfreezes. I just can't figure it out .
What i did now:
IF > commentCheck = 3*commentPage-2 > Do action
IF > commentCheck = 3*commentPage-1 > Do action, Do Action
IF > commentCheck = 3*commentPage > Do action, Do Action, Do Action
commentCheck = The number of comments
commentPage = The comment page
I think i'm stuck at the pages.
If i got 1,2 or 3 comments everything works perfect as mentioned above. Now the problem starts having a 4th comment.
If i have 4 comments the formulas above don't work anymore if the commentPage is still 1. This makes sense but i am not sure how to switch over.
Even if commentCheck = 4 but i am still on comment page 1 it should show the first 3 comment.
The information is always right in my php script no matter the page because i use limit 0,3 if the comment page is 1, i use limit 3,6 if the comment page is 2 and so on.
So my information is always correct in my script.
So if i have 4 comments but commentPage = 1 it should read it as 3 comments. Once a user hits the "More comments" button commentPage will be 2.
My conclusion: commentCheck = commentCheck(4) - commentPage(1). So if i have 4 comments, and i'm on page 1, it will be counted as 3 and it will create 3 comment blocks.
If i go a page up, the new calculation will be commentCheck = commentCheck(4) - commentPage (2) which results in 2. This is incorrect. Because it should be 1.
I am really not getting the clue here .
My code so far:
i really dont understand what your trying to do...so many comments
your changing the formula here not the variable.
The formula should stay the same you just need to change the commentPage variable.
f(x)=3x-2 is a linear function you put a x in and get a f(x)=y out.
Never change the parameters (3 and -2) or you will get another function or even a cluster of function if the parameter is a variable itself.
So maybe you should do something like that:
set commentCheck to 3*commentPage-2
...........if commentCheck=1--->do something
...........if commentCheck=4--->do something
...........and so on
But as i said i dont get what your trying to do with this.
It sounds like you just want to switch to a new comment page every 3 comments?
Yes, i indeed really have trouble explaining my question since i don't understand it myself .
I indeed want to switch to a new comment page each 3 comments. That's why i have 3 different formula's. I think this is needed because first it will show comment 1,2 and 3. Switching pages should show 4,5,6.
The reason i think this is the only way is because it's possible to have like 4 or 5 comments. If for example the case is 4 comments it should not trigger the second and third formula after switching to the second page. Because that would create a object for comment 5 and 6, which obviously do not exist if there are only 4 comments. That's why i need to know how to get do a action each 1,4,7 etc.
This is the result for one comment
This is how my php script shows how many comments there are
In the database ( no clue why i shot this screenshot )
The comment background object is created because of this
When i added another comment
Because my php script showed there were 2 comments
As you can see in the screenshots everything works as planned.
If i add a third comment the third comment will show up.
Once i add the 4th comment none will be created. This is where it goes wrong.
So, if i got 4 comments my php script will result a 4. Just like the 1 and 2 shown above.
The fact is that i first want to run the formulas for 1,2,3. After clicking the red arrow at the bottom of the screen i want to show comment 4.
So in fact comment 4 would be on page 2.
So if i take this image:
What it should do, if we take 4 comments, is running all 3 actions. Once i click the "next page" button it only has to run action 1 again since that will add up to 4, aka the amount of comments. So if we take 5 comments for example. It again, has to run all 3 actions. After clicking the next page button it will only have to run action 1 and 2.
P.s. Don't mind all the other info at the php script. This i can assign to each comment block once my issue is solved.
I thought about a nice system but its a bit complicated.
But i just got an easier idea.
Every comment is a block in your script?
So just count the blocks. Give them a variable called commentNUmber.
And a global variable TotalComments
on comment made add+1 to TotalComments and set the instanze commentNUmber to TotalComments.
then make a new block at (x=360,y=859+(commentNUmber-1)*133)
so every comment will create a block 133 pixel under the last block
then if you klick the downarrow just shift all blocks up(-) 133 pixels.
on uparrow shift them down(+) 133.
So you can just "scroll" through them. No need for Pages.
Its getting late my english is getting worse i am sorry

I've been thinking that way but the thing is that these comments are getting fetched from a database.
I know i might have high hopes but if this app really works out it could be possible that 1000's of comments will be added.
There is no way i can pre-load 5000 comments creating 5000 objects. Somewhere i have to cut it off anyways.
It's also getting late for me i will re-think this trough tomorrow.
The combo semi-knowledge of Construct 2 and almost no knowledge of math formulas kills it for me .
Ok then you need to stick to the three blocks and just load the comments into them from an array(database).
Thats totally possible with some math magic.
Alright! Massive facepalm time !
I actually created the system before with some bugs. Thought to throw it all around and re-create it ending up in this mess.
Finally figured it out how to do it. Thing is, i had it almost completely right the first time.
Anyways this is how.
Instead of checking how many comments there are for creating the comment blocks i simply check if the comment is empty or not ( duh! ).
So if comment 1 and 2 are there, it will create 2 blocks. As comment 3 is empty, aka does not exist, it will stop right there.
Now for the 3 comment limit, that's why i put up a limit in my php script in the first place. This is also how i check if my comments are empty.
So all there was left was the "next page" button.
This i've done by:
ceil(commentCheck/3) =< commentPage > Delete button
ceil(commentCheck/3) > commentPage > Create button
Problem solved .
Thanks for the brainstorming with me .
This is what it looks like:
variable l1 and l2 are the limits i send to my php script, so it will only show 3 comments.
