Cave Circle of Light Effect...

[Kraft]

Hey, while back Sephiroth gave me a script that places circles of light around the player and events when all the lights go out. I know how to do this with a pic placed ofer the screen, but I also want it around key events (such as torches, fires, lanterns, etc)

I have the script, but it is very laggy if there is more than 2 or 3 circles in the map, or if the circles are too big.

I love the script, I use it a lot, but I would like to know if there is anything that anyone (mainly seph) could do to improve the framerate, and possibly instead of a hard edge for the circle (ie, it does not fade to black, it is a hard edge) make it fade out around the edges a little.

You (seph) said that you would try it a while ago, and possibly use an pic instead of making the circle in the script.

Is there an update on this? If not then I will request one please.
If you need the script, here it is...

I have an updated version that uses pics, the problem being that if your pictures overlap, you end up drawing over one circle, so it doesn't work perfectly.

I still recommend it, since you can use the pics for events that don't move, and just use the bitmap draw_circ method for the player and moving objects.

I will try to dig it up and do a little work on it tomorrow at work.

 

[Kraft]

Cool, thanks!

Also, I have one thought...
could you make it so that if I were place a comment (such as "Guard") and a script switch into an event (the event I am thinking of would be a guard) and the player enters that circle of light around the event, it switches on the switch in the event?

This would be used in a dark room, where guards are patrolling, and if the players feet (the unit/square that he is standing on, not the circle of light around you) enters the guards, it flips the switch defined in the event.

Or possibly a Self-switch, if possible, so I dont have tons of switches.

This would also be useful in a lighted room, just dim the lights a tiny bit, so that you can see the circle of light around the guard, and avoid it.

That way I could make the guards patroll.

Thanks,

Kraft

 

[SephirothSpawn]

Not a bad idea. I am thinking of some way to do this better anyways, so I can throw this in there as well.

 

[Kraft]

bump. ( I would like to have thin in my Demo that will be released soon (well, kinda soon, it still needs lotsa work)

[SephirothSpawn]

I am still trying to think of the best way around this. Drawing circles seems to take forever, but picture overlap.

None the less, I will start on this now.

 

[Kraft]

thanks man!

 

[SephirothSpawn]

Ok. Here's a demo I did. Took a bit longer than I thought, but yeah.

Demo

Let me know if you don't understand anything. It's time for a break for me. I will be back in probably 30 minutes - hour to answer any questions you may have.

 

[Axerax]

I will have to try this, I tried using the older version a while back and it was really buggy, I'm excited to see this brought back

 

[Kraft]

one question...

Is it possible with this script to change the size of the circle around the events?

and in the script, where it says effected maps, Yes I understand that I need to put the map ID #'s there, but if I were to add more than one, would I just use a comma?

Thanks!

Kraft

Edit,

Also, Is it possible to change the players circle of light radius in the game?
with a script call or something?

 

[SephirothSpawn]

Hehe. Instructions coming now.

Defaults:
~ Affected Maps : Affected_Maps = [map_id, ...]
~ Default Cover Color : Cover_Color = Color.new(r, g, b, a)
~ Player Radius : Player COL Radius = n or 'filename'

Circle of Light Customizables
~ Turning On or Off Via Script
$game_map.cavelighteffects.on = true or false
~ Turning Player On or Off Via Script
$game_map.cavelighteffects.player_on = true or false
~ Changing Player Radius
$game_map.cavelighteffects.player_radius = n or 'filename'

Event Setup
~ Setting Radius (Using Draw Circle Method)
Comment : CIRCLE OF LIGHT *
~ Setting Radius (Using File BLT)
Comment : CIRCLE OF LIGHT (filename)


Setting Circle of Light Manually for events
$game_map.events[event_id].col_radius = n or 'filename'



n = Number
'filename' = Picture Filename in Pictures Folder


It draws the highest number event first and the player last. Example : 8, 6, 5, 4, 2, 1, Player, so I suggest making stationary objects your high events and using draw circle methods for moving events / player with low event ids.

You can use files to transfer for the player or the draw circle. If you define a number, it uses the draw circle command. If you specify a string ('filename'), it uses a picture from the picture folder.


I didn't do the Event trigger, but that can be done with Near's Event Triggers with his View Range Module.

I tried this system and like the way it works, but I have run into a bug with the pictures.

When setting a picture to the player rather than the "circle" I get this error.

Undefined method 'player_rad' for #<Game_CaveLightEffects:0x67603c8>

This only happens when the character is set to use an image, events work fine.

 

[SephirothSpawn]

$game_map.cavelighteffects.player_radius = n or 'filename'

player_radius, not player_rad

 

[sixdd]

ah, my mistake, surprised I didn't catch that myself XD Thanks a lot
