Navigation Line

[Hellfire Dragon]

I want a Navigation Line script, like th eone in dead space. For those who didn''t play dead space, basically, when a certain button is being held down a glowing blue line would appear and yo could follow it to your next objective. I want it so I can turn it on and off too.

I thought about this and it wold probably be hard, especially when the objective is on another map. Well I don't know, I'm not a scripter but if anyone thinks they could give this a try, could you please

[Fantasist]

I didn't understand the "line" part. If it's an arrow which points to the destination, then it's fine.
Yeah, pointing to something on a different map is a problem. Though, you can point to the teleport event in every map manually. If that's the case, I think I can pull this off.

[Hellfire Dragon]

Yeah that'd work fine, the line, well in dead space a blue line appears along the ground and if you follow it you get to the objective, the arrow is fine though and it's probably way easier.

This would be an awesome script. Good luck Fantasist hope you can pull it off!

This is also in a game called Legendary. You hold down a button and there's a line to your next objective.

Okay. I'll give it a shot. It should take 20 mins max, but I need to be able to concentrate. I'll do it within 2 days.

EDIT:

I have the first draft. It's getting late, so I'll update the script header later (the instructions). Here's the demo:

Tell me if you need anything else.

Its great! I think he wanted to only be activated if a certain button is being held down. But great Fantasist this is just pure awesomenes.

[Hellfire Dragon]

That's great! That you Fantasist But like GG said, I wanted it to only appear when a button is being pressed. I'm using Blizz ABS so I wanted it something like, it appears/disappears when the player press 'P' Or something like that. Maybe if you can have it activating with like, whatever = true/false I could just make a common event for it.

[Fantasist]

Glad you like it
I forgot about the button being pressed. No need to make a common event, it's easy to implement. Also, if you checked out the events in the demo, you can turn it off by using:

$game_temp.point_towards(nil)

nvm, I'll update this tonight.

Wow, awesome script!
This might really come in handy - better than having to talk to NPCs... XD

# ** Map Target Pointer
#------------------------------------------------------------------------------
# by Fantasist
# Version: 1.0
# Date: 30-Jan-2009
#------------------------------------------------------------------------------
# Version History:
#
#   1.0 - First version
#------------------------------------------------------------------------------
# Description:
#
#     This script adds a pointer which points to a desired event on the map.
#------------------------------------------------------------------------------
# Compatibility:
#
#     Should be compatible with almost everything.
#------------------------------------------------------------------------------
# Instructions:
#
#     Place this script in a new slot below Scene_Debug and above main.
#   If you're using any input modules and the key you set is from that script,
#   plave this below that input script.
#
#   Use the following call script to set a target event:
#
#         $game_temp.point_towards(EVENT_ID)
#
#   where EVENT_ID is the ID of the event to which the pointer should point.
#
#   To remove the target, use:
#
#         $game_temp.point_towards
#                   or
#         $game_temp.point_towards(nil)
#------------------------------------------------------------------------------
# Configuration:
#
#     Scroll down a bit for configuration.
#
#  MTP_Pic: Name of the picture file in the "Graphics/Pictures" folder.
#           The pointer should point upwards.
#  MTP_Position: Position of the pointer.
#                 - If it is fixed, use an array of X and Y values
#                   (like this: [X, Y]) if the pointer is static.
#                 - Use nil for placing the pointer above the player.
#  MTP_Key: The key which should be pressed for the pointer to appear.#
#------------------------------------------------------------------------------
# Issues:
#
#     None that I know of.
#------------------------------------------------------------------------------
# Credits and Thanks:
#
#    - Fantasist for making this.
#    - Hellfire Dragon for requesting this.

EDIT: Oh, and thank you guys

[Shadonking]

this could be really cool with a few other options. e.g. for the pointer to point at coodinates using variables.

also i seem to be having trouble getting the the pointer to work when pressing a key, if you leave it as A it started up but i use that to walk but if you change it to any other key it comes up with errors.

[Hellfire Dragon]

Actually it does work with other keys, but only the ones built into rmxp, so for Q you'd set it to L. Awesome work Fantasist So other than than only being able to use the rmxp keys, this script is great

[shdwlink1993]

To use other keys (provided you're using Ton's Input), you use this (I think ):

Input::Key['A']

[Shadonking]

i see if L uses the Q key what do you put in to use P.

[Hellfire Dragon]

The rmxp keys don't cover the whole keyboard They only cover, the arrow keys,Z, X, C, Q, W, A, S, and D.

@shdw I don't know if that would work, I only tried using that with the blizz-abs. I'll check though

[Shadonking]

thats a shame, but at least there is one key there that im not using which is Z but i dont now what to put in for that key to use.

[Fantasist]

Woah, wait a second guys, it'll work with any input module.

# Instructions:
#
#     Place this script in a new slot below Scene_Debug and above main.
#   If you're using any input modules and the key you set is from that script,
#   place this below that input script.

Basically, if you're using Tons or Blizz-ABS, both of them have the same input module, so what shdwlink said would work:

To use other keys (provided you're using Ton's Input), you use this (I think ):

Input::Key['A']

So for p, it's:

Input::Key['P']

If you're still getting errors, here is the workaround:

In the config, comment out the MTP_Key option:

  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  # CONFIG BEGIN
  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
 
  MTP_Pic = 'Target_Pointer'
  MTP_Position = nil #[320, 240]
  MTP_Key = Input::A # <<<<< Comment this out!!
 
  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  # CONFIG END
  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Then paste the following snipped BELOW any input modules you're using. So this snippet goes below Tons and/or Blizz-ABS:

#==============================================================================
# ** FTSConfig (MTP key workaround)
#==============================================================================
module FTSConfig
  
  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  # CONFIG BEGIN
  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  MTP_Key = Input::A
  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  # CONFIG END
  #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  
end

Glad you guys like it

@Shadonking: That's an interesting feature, pointing to coordinates. I'll remember that

[Shadonking]

ok im not using tons input and im using blizz abs controlles and i have place the script under both of them but certian keys keep coming up with errors, i even just tried that little snippit thing you just posted but the same error came up when tring to use P.

also what would be cool would to have an option to turn it on and off with a swith then people could use this script as an item or skill.

[Hellfire Dragon]

I was just going by the Where to put Blizzards scripts thing, it says to put other people's script above the abs. Anyway I'll try what you said out

[Aqua]

Nice script Fanta!

I'll definitely use it in my game (unless like... I don't find a need for it... but who wouldn't need this!?! )
