Animation of storm

Post by serclino »

Hi guys,

is it somehow possible to make an animation of storm hitting certain hex? I mean animation of Delfador's range attack, but without Delfador's presence. :D

Can anybody help?

Thanks!

Hi there!
I assume you want to include your lightning as a part of some (start/moveto/???) event. In that case, you can easily animate a lightning by including this macro into your scenario file:

EDIT: Changed the LIGHTNING_HITS_HEX macro to circumvent a bug related to [remove_image]. (suggested by vghetto)

Code: Select all

#define LIGHTNING_HITS_HEX X Y
[set_variable]
    name=random_lightning
    rand="1,2,3"
[/set_variable]
[sound]
    name=lightning.ogg
[/sound]
[item]
    x,y={X},$({Y}-2)
    halo=halo/lightning-bolt-$random_lightning|-[1~4].png:100
[/item]
[delay]
    time=400
[/delay]
[remove_item]
    x,y={X},$({Y}-2)
    halo=halo/lightning-bolt-$random_lightning|-[1~4].png:100
[/remove_item]
[clear_variable]
    name=random_lightning
[/clear_variable]
#enddef
Whenever you want to display a lightning animation onto some hex, use the newly defined {LIGHTNING_HITS_HEX X Y} macro.
One example:

Code: Select all

[event]
    name=moveto
    
    [filter]
        side=1
        x,y=10,5
    [/filter]
    
    {LIGHTNING_HITS_HEX 10 5}
[/event]
In this case, the poor unit that moves to the hex x,y=10,5 gets struck by a lightning! Luckily for the unit though, it receives no damage :D

MoonyDragon: Thank you :-) This is exactly what I've wanted. However, few days ago I found another solution, which also works for me. But I forgot to update this thread, that my problem is solved.
Still thank you for defining this variable for me (I'm not familiar with this yet).

Here is another way how to do it. Maybe someone with same task like me can use it later.

Code: Select all


	[item]
            x,y=10,5
            halo=halo/lightning-bolt-1-1.png
        [/item]

        [delay]
            time=50
        [/delay]

        [item]
            x,y=10,5
            halo=halo/lightning-bolt-1-2.png
        [/item]

        [delay]
            time=50
        [/delay]

        [item]
            x,y=10,5
            halo=halo/lightning-bolt-1-3.png
        [/item]

        [delay]
            time=50
        [/delay]

        [sound]
            name=lightning.ogg
        [/sound]

        {FLASH_WHITE ()}

        [item]
            x,y=10,5
            halo=halo/lightning-bolt-1-4.png
        [/item]

        [delay]
            time=400
        [/delay]

        [remove_item]
            x,y=10,5
        [/remove_item]

There is a problem with this code because remove_item is broken, there's github ticket about it somewhere.
The remove_item code will remove all images from your map, not just the lightning_image. I know because that's what happened to me when I tried using the LIGHTNING_HITS_HEX macro for my mod :)

The issue you are referring to exists only in wesnoth 1.15.2+dev, so for most users here, this is no reason to panic :lol:
But if you happen to use the most recent developmental (use with caution) version, you can make the code work nonetheless.
In the link, doofus-01 specified that the issue does not apply when coordinates are given, so simply change

Code: Select all

[remove_item]
    name=lightning_image
[/remove_item]
to

Code: Select all

[remove_item]
    x,y={X},$({Y}-2)
    name=lightning_image
[/remove_item]

I'm not sure how you concluded that this exists only in 1.15.2+dev? I used 1.14.9 and it happened with that.
Yes, the addition of the x,y will not remove all other images, but it will remove all images occupying that hex (which is 2 hexes above where the player moved to) along with the lightning. I did try to add halo= and image= to remove_item but those didn't work. I even tried to spell out the remove halo path and wrote multiple remove_item with the expanded -[1~4].png part. No luck.
Switching the [item] from halo to image broke the lightning effect for me.

Edit: ok, this seems to fix it. I left out the :100 part in my previous attempts.
The name=lightning_image line is superfluous.

Code: Select all

[remove_item]
    x,y={X},$({Y}-2)
    name=lightning_image
    image=halo/lightning-bolt-$random_lightning|-[1~4].png:100
[/remove_item]

You are absolutely correct. I used the versions 1.14.9 and 1.15.2 without ever noticing such a bug. In this regard, I first heard of it from you :lol:
Doofus-01 reported to play on 1.15.2+dev when reporting this bug, so I assumed (since I used 1.15.2 in total ignorance of it) that it was restricted to this version.
Concerning the code itself, I will update it to include your (bug-proof) solution.
