I need help on my rpg I'm making.

I am making an rpg game in clickteam fusion. But I don't know how to get dialogue to work. Here's the mfa file. Here are some problems with the game.
when you talk to lemon guy you can move
after you talk to the lemon guy and then go to your inventory the empty boxes say what the lemon guy said.
also when you get out of the inventory you can't move.
I will be very happy if someone can fix this for me and explain what they did.

Hi,

the main problem lies in immediate conditions (green lines)
being triggered instantly in succession when an action occurs

so that, if you say:

player press fire 1
+flag 0 OFF
>>> do this
>>> set flag 0 on

player press fire 1
+flag 0 ON
>>> do that

on pressing fire 1, both actions will be triggered
(because second in the list will find flag 0 set to ON by previous in the list)

to avoid this, you can i.e. "toggle" a flag on button press (toggle means that if flag is 0, will become 1, and reverse)
an then code your actions for flag ON or OFF,
in this way things will happen only once, and no double-action will be triggered

See modified example:

I quite don't understand but thank you for trying to explain this to me! This is probally my first attempt at a rpg with dialogue.

what do I do if I want the npc to continue talking?

Well, I guess a complete dialogue system may require a much more careful planning.

Here's an example with two paragraphs and "skip" to end of line:

The key element here is making sure you only trigger one action per button pressed,
in this example I've used flags instead of button press, to detect actions to perform,
because I think in this way we can have a better control inside the event flow.

On button press, we set FLAG2 on,
when flag2 is on, we do something, than immediately turn flag2 off, so that other events won't trigger.

If we just did on button1 press do this, on button1 press do that, both "this and that" would have happened, making for bad results.

I somewhat understand, I have a lot to learn. Barely two month ago I learned what flags were and I was thinking to myself, "This changes everything!"

Also, I encountered a problem. If the player presses fire 1 even when the interact box is not overlapping the npc then later the interact box overlaps the npc the npc starts talking.

Nevermind, I fixed it.

How do I make it so another Npc can talk? Please use this mfa file. http://intertrash.weebly.com/uploads.../project_2.mfa

You probably need a slightly different approach,
you have to link each NPC to their own speech
and if you are going to build a vast world, it's likely that you'll benefit from a database structure

you could even use a simple list object,
a list can store both text lines and ids ("set line data")

so that you can have i.e.

id line text
1 1 hello I'm character 1
1 2 and this is my second line
2 3 wait, I'm character 2 now

all you have to do then is storing in each npc their own ids,
so that next time your player will interact with them
you will parse the list and retrieve first line paired to that id
then second line etc. until next line has a different id
(means that it's another character speaking)

a better performing and more flexible solution could imply using a text array,
but maybe you can start easier with a list and see how it goes

I think maybe you should start out with something more easy. Making a rpg is a huge job ( making one myself) but if you have problems with these things already...well...it's gonna get a lot harder for you. I don't say this to push you down, i'm just saying that you might end up really frustrated and give it all up. I always wanted to make a rpg so i know how you feel probably :-D...but making dialogs is imo a very easy thing to make so take your time and learn the basics before tackling the monster known as RPG. And as mentioned...not trying to sound bad...just a friendly advice :-)

I'm taking that advice as I'm hoping to make an RPG myself one day. Is this your first game? Then I suggest this video for a bit of guidance...

Not my first game at all :-) if you need help further on i can give some pointers maybe. I have a fully functioning turn based battle system...questlog etc :-)
