I am revamping the combat system for my current horror game. I would like it to go some thing like this:

You enter room where there is a monster.
You get the message: You hear growling.
You have 3s/1turn to get out of the room before being attacked.

Also, the monster is roaming, so i need the game to check each time you enter a room if the monster is there. I have tried everything i can think of. If possible please explain in the GUI editor, I'm bad at coding.

I can't explain via the GUI~Editor very well, but hopefully I can provide some guidance, which you can figure out how to do it in the GUI~Editor, though hopefully someone else will help you with doing it in the GUI~Editor, anyways here's my attempt, lol:

there's two global checking options for what you want to do:

1A. add a 'changedparent' Script Attribute to your 'XXX' Player Object:
1B. same as 1A, but for your 'monster' Object, instead.

'player' Player Object -> Attributes (Tab) -> Attributes -> Add ->

Attribute Name: changedparent
Attribute Type: script
Attribute Value_or_Expression: (see below)

run as script -> add a script -> scripts -> if -> [EXPRESSION] -> write~type in (see below):

your_monster_name.parent = your_player_name.parent

or, in Code: if (your_monster_name.parent = your_player_name.parent) { scripts }

then, add a script -> output -> print a message -> [MESSAGE] -> You hear growling.

or, in Code:

if (your_monster_name.parent = your_player_name.parent) {
  msg ("You hear growling.")
}

and lastly,

you need to create a global Timer (see below using the 2. Turnscript option of how to create a global Tmer, it's last script is to disable it after the 3 seconds), which you then enable within this (changedparent) script:

(same indenting level as your first 'then' script) -> add a script -> ??? -> enabled timer -> name_of_your_timer)

if (your_monster_name.parent = your_player_name.parent) {
  msg ("You hear growling.")
  // enable Timer script, I'm not sure what it is in code, lol. Maybe it's just a 'call', thus using merely it's name, but I'm not sure.
}

lastly for the /1 turn, create a global turn:

'game' Game Object -> Attributes (Tab) -> Attributes -> Add ->

Attribute Name: turns
Attribute Type: int (integer)
Attribute Value: 0

and also this too:

'game' Game Object -> Attributes (Tab) -> Attributes -> Add ->

Attribute Name: old_turns
Attribute Type: int (integer)
Attribute Value: 0

and *back within your global timer*, add these 2 scripts at the bottom~last:

run as script -> add a script -> variables -> set a variable or attribute ->

left of the equal sign: game.old_turns
right of the equal sign: game.turns

game.old_turns = game.turns

run as script -> add a script -> variables -> set a variable or attribute ->

left of the equal sign: game.turns
right of the equal sign: game turns + 1

in code: game.turns = game turns + 1

and at the start~top of your global timer, add this script:

if (game.turns = game.old_turns + 1) {
  // your 'fight~encounter' scripts
}

your global Timer's code in full:

if (game.turns = game.old_turns + 1) {
  // your 'fight~encounter' scripts
  // 'disable this global Timer' script
}
game.old_turns = game.turns + 1
game.turns = game.turns + 1

2. global Turnscript:

(too tired at the moment, lol, if I can I'll get around to explaining how to do it this way)

-------------

hopefully, this is error free... but that's unlikely, lol.

ask if you need help with any of this stuff...

------------

ach, this is incorrect design... for the global timer, as the 'if' conditional part of the scripting needs to be removed from the global timer, to instead as a 'changedturns' script on~in~within the 'game' Game Object. meh... sorry...
