how to customize sprite

[spare geyser]

i tried this:

sprite = new Sprite(GFX.Game, "HeartWars/FireBall");
Add(sprite);

it crashed and said System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

but this works:

FireBallTexture = GFX.Game["HeartWars/FireBall"];

if you actually want a custom sprite with animations etc., you need a custom sprites xml. see for example Flag Pickups in max' helping hand:

https://github.com/max4805/MaxHelpingHand/blob/master/Graphics/Sprites.xml#L20

what should i do if i don't want animations

HeartWars/FireBall isn't a folder but a file

now it's at Graphics\Atlases\Gameplay\HeartWars\HeartWarsFireBall\idle00.png

and here is my Sprites.xml:

<?xml version="1.0" encoding="utf-8" ?>
<Sprites>
    <HeartWarsFireBall path="HeartWars/HeartWarsFireBall">
        <Justify x="0.5" y="0.5" />
        <Anim id="idle" path="idle" delay="0.1" frames="0" />
    </HeartWarsFireBall>
</Sprites>

it doesn't work

game crashes when i execute this.sprite.Play("idle", true, false);

what happens if you make it a 2-frame animation, with the same frame twice? i.e. copy the image, rename it so there's an 00 and an 01, and make it animate between them?

i'll try

<?xml version="1.0" encoding="utf-8" ?>
<Sprites>
    <HeartWarsFireBall path="HeartWars/HeartWarsFireBall">
        <Justify x="0.5" y="0.5" />
        <Anim id="idle" path="idle" delay="0.1" frames="0-1" />
    </HeartWarsFireBall>
</Sprites>

this.sprite.Play("idle", true, false);

still crashing

there is Graphics\Atlases\Gameplay\HeartWars\HeartWarsFireBall\idle0.png and Graphics\Atlases\Gameplay\HeartWars\HeartWarsFireBall\idle1.png

i tried GFX.SpriteBank.Create("HeartWars/HeartWarsFireBall")

and got this

System.Exception: Missing animation name in SpriteData: 'HeartWars/HeartWarsFireBall'!
   at DMD<Monocle.SpriteBank::Create>(SpriteBank this, String id)

Sprites.xml:

<?xml version="1.0" encoding="utf-8" ?>
<Sprites>
  <HeartWarsFireBall path="HeartWars/HeartWarsFireBall">
    <Center/>
    <Anim id="idle" path="idle" frames="0"/>
  </HeartWarsFireBall>
</Sprites>
