Earthquakes events and kill units in a precise area

[Graziani]

Hi wesnoth community!

I have a question about earthquakes in Wesnoth (like in burning suns in final confrontation for example).

In the burning suns xml, i found this

Code: Select all

  [scroll]
            x=25
        [/scroll]
        [scroll]
            x=-25
        [/scroll]
        [scroll]
            x=25
        [/scroll]
        [scroll]
            x=-25
        [/scroll]
        [scroll]
            x=25
        [/scroll]
        [scroll]
            x=-25
        [/scroll]

        [redraw]
        [/redraw]

        [delay]
            time=400
        [/delay]

        [color_adjust]
            red,green,blue=40,0,100
        [/color_adjust]

        [redraw]
        [/redraw]

        [delay]
            time=250
        [/delay]

        [color_adjust]
            red,green,blue=0,0,0
        [/color_adjust]

        [redraw]
        [/redraw]

I presume that scroll is for the view, it's shake all the screen up and down.

But delay, color and redraw, what is it? I mean how use it to create some colors in the earthquake?


A last question, i would like to make an event that kills every units that are in a precise area (because of earthquake) with a change of terrain. I know how to modify terrain, but to kill the units i don't know at all how to do



Thanks in advance for your responses!

But delay, color and redraw, what is it?

[scroll] is used to shake the screen by scrolling back and fourth by 25 pixels, [color_adjust] changes the color to a specified RGB value, [redraw] redraws the screen, [delay] creates a pause, the value is the duration given in milliseconds. To create an earthquake-y effect, you could use the same code and modify the values/add more/different colors.

A last question, i would like to make an event that kills every units that are in a precise area (because of earthquake) with a change of terrain. I know how to modify terrain, but to kill the units i don't know at all how to do

To kill units, use the [kill] tag. You can specify the area where you want to eradicate everything as a Standard Location Filter inside the Standard Unit Filter, like this

Code: Select all

[filter]
  [filter_location]
    x=1-20
    y=1-15
  [/filter_location]
[/filter]

to create an earthquake effect, you better use the EARTHQUAKE macro

Code: Select all

{EARTHQUAKE (put your kill tag or any other action wml in here)}

[Graziani]

Thanks a lot both of you i'm going to try the two codes!

[Graziani]

Code: Select all

[kill]
[filter]
  [filter_location]
    x=1-20
    y=1-15
  [/filter_location]
[/filter]
[/kill]

Strangely, every unit on the entire map is killed by this event... I tried some issues but everytime all the units are getting killed.

Empty filter matches all units. You should reread the reference http://wiki.wesnoth.org/DirectActionsWML#.5Bkill.5D.

To kill units, use the [kill] tag. You can specify the area where you want to eradicate everything as a Standard Location Filter inside the Standard Unit Filter, like this

Code: Select all

[filter]
  [filter_location]
    x=1-20
    y=1-15
  [/filter_location]
[/filter]

Except as the link says, don't use a [filter] tag. Also, you don't need to wrap x= and y= in a [filter_location], because those are part of StandardUnitFilter too.

[Graziani]

Code: Select all

[kill]
  [filter_location]
    x=1-20
    y=1-15
  [/filter_location]
[/kill]

It works perfectly like this. Thank you !

Hello guys, I'm opening again this topic after five years to ask you again about earthquakes.

I really want to shake the screen and all my attempts are failing, I don"t like the result.

I tried this :

{EARTHQUAKE (
[sound]
name=rumble.ogg
[/sound]
)}

For this one, There is some lightning sound and the screen is shaking for less than one second, and it's a very small movement.

and I tried this :

Code: Select all

 {REPEAT 5 (
     {QUAKE "rumble.ogg"}
 )}

Even if it's close to what I want, the repeated sound is not clean and disturbing. The shake effect is good if you repeat x15/20 but the sound become horrible when you do so.

and I tried this (UTBS last level)

Code: Select all

  [scroll]
            x=25
        [/scroll]
        [scroll]
            x=-25
        [/scroll]
        [scroll]
            x=25
        [/scroll]
        [scroll]
            x=-25
        [/scroll]
        [scroll]
            x=25
        [/scroll]
        [scroll]
            x=-25
        [/scroll]

        [redraw]
        [/redraw]

        [delay]
            time=400
        [/delay]

        [color_adjust]
            red,green,blue=40,0,100
        [/color_adjust]

        [redraw]
        [/redraw]
       

        [delay]
            time=250
        [/delay]

        [color_adjust]
            red,green,blue=0,0,0
        [/color_adjust]

        [redraw]
        [/redraw]

But it doesn't work.

I'm kinda lost, I cannot find something useful in the forums, if you guys can help me. In the scenario, a cave is going to rumble on itself, and I really want a big screen shake.

Thanks in advance !

If you liked the results of

Code: Select all

{REPEAT 5 (
     {QUAKE "rumble.ogg"}
 )}

and it's just the sound that troubles you, then you could just play sound with the first one.

If you include an empty track called "silence.ogg" with your add-on, then it's just:

Code: Select all

{QUAKE "rumble.ogg"}
{REPEAT 4 (
	{QUAKE "silence.ogg"}
)}

Otherwise you just manually expand what the macro means, and omit the sound:

Code: Select all

{QUAKE "rumble.ogg"}
{REPEAT 4 (
    [scroll]
        x=5
        y=0
    [/scroll]
    [scroll]
        x=-10
        y=0
    [/scroll]
    [scroll]
        x=5
        y=5
    [/scroll]
    [scroll]
        x=0
        y=-10
    [/scroll]
    [scroll]
        x=0
        y=5
    [/scroll]
)}

OMG I never thinked about using the silence.ogg !!!

Thank you so much WhiteWolf ! It's very useful, even the second one you gave me, that allow to manually adjust !
