Dans ce code, l'explosion ne s'exécute que quand on tire en même temps.
voici mon test :

JavaScript:

console.log(explosing[baril].heal);

Output : explosion sans tirer :
0
la vie du baril a été mise à 0, mais pas d'explosion
Output : explosion en tirant :
[75] 0
la vie du baril a été mise à 75 fois à 0, explosion.

Aide-moi stp, je veux que le baril explose sans qu'on ai à maintenir le clique pendant l'explosion.

Dans ce code, l'explosion ne s'exécute que quand on tire en même temps.
voici mon test :

JavaScript:

console.log(explosing[baril].heal);

Output : explosion sans tirer :
0
la vie du baril a été mise à 0, mais pas d'explosion
Output : explosion en tirant :
[75] 0
la vie du baril a été mise à 75 fois à 0, explosion.

Aide-moi stp, je veux que le baril explose sans qu'on ai à maintenir le clique pendant l'explosion.

Il semble que le problème soit lié à la condition `if (barilExplosion.currentStat == true)` dans la boucle de dessin. Cette condition empêche la partie de dessiner les particules d'explosion si `barilExplosion.currentStat` est faux, ce qui est le cas quand il n'y a pas de clic en cours. Pour corriger cela, vous pouvez déplacer le bloc de dessin des particules en dehors de cette condition. Voici un exemple de modification du code :

```
function draw() {
// ...

if (barilExplosion.currentStat) {
particlesNumber = 360;
particles = [];
for (let i = 0; i < particlesNumber; i++) {
// ...
}

ctx.fillStyle = "rgba(255, 255, 255, " + opacity + ")";

for (let i = 0; i < particlesNumber; i++) {
ctx.fillRect(barilExplosion.posx + explosive[0].width / 2 + particles.posx - player.posx, barilExplosion.posy + explosive[0].height / 2 + particles.posy - player.posy, 8, 8);
}
}

// ...
```

Maintenant, les particules devraient être dessinées même sans clic.

dans un jeu html, quand je double clique sur l'écran, ça me sélectionné en bleu le text (comme le nombre de balles restantes qui est une information qui ne devrais pas être sélectionnable), comment faire?

Pour éviter la sélection du texte sur double-clic, vous pouvez utiliser l'attribut `onselectstart` sur l'élément dans lequel vous ne voulez pas de sélection. Cet attribut empêche la sélection de tout le contenu dans l'élément lorsqu'il est activé.

Voici un exemple de code HTML avec l'attribut `onselectstart` appliqué à un paragraphe :

```html
<p onselectstart="return false;">Texte qui ne peut pas être sélectionné</p>
```

Notez que cela empêchera la sélection de l'intégralité du contenu de l'élément, mais autorisera toujours la sélection de parties individuelles du texte.

Si vous souhaitez désactiver la sélection sur l'ensemble de la page, vous pouvez utiliser cette propriété CSS :

```css
* {
user-select: none;
}
```

Cela empêchera toute sélection de texte sur la page sauf si vous l'autorisez expressément sur un élément spécifique.

Dans mon code, quand le baril explose, d'abord la vie reste à 100, puis quand on bouge, elle descends sans cesse, ce qui fait que, avec la fonction play(); la vie oscille très vite entre 100, 20 et 0 puis quand on est dans un rayon de 600 px du baril qui n'existe plus et qui n'est pas censé exister, l'oscillation cesse mais quand on s'en éloigne à nouveau, l'oscillation revient.

Un explosif n'explose qu'une fois, donc je veux que la vie baisse de 80 puis c'est tout. en suite dans un jeu les dégâts doivent être immédiats, et non attendre qu'on bouge pour apparaître.

voilà. Bonne chance pour résoudre tout ça.

Dans mon code, quand le baril explose, d'abord la vie reste à 100, puis quand on bouge, elle descends sans cesse, ce qui fait que, avec la fonction play(); la vie oscille très vite entre 100, 20 et 0 puis quand on est dans un rayon de 600 px du baril qui n'existe plus et qui n'est pas censé exister, l'oscillation cesse mais quand on s'en éloigne à nouveau, l'oscillation revient.

Un explosif n'explose qu'une fois, donc je veux que la vie baisse de 80 puis c'est tout. en suite dans un jeu les dégâts doivent être immédiats, et non attendre qu'on bouge pour apparaître.

voilà. Bonne chance pour résoudre tout ça.

le problème est résolu depuis. Sans l'aide de chatGPt, lui, il décone
