If you just want the death anim not to loop: https://forums.rpgmakerweb.com/index.php?threads/sideview-battler-death-animation.92148/#post-836168The dead sprite won't exactly work, since there are 3 frames it'll loop those 3 ceaselessly, so like in the example I gave, if an enemy blows up upon dying, we'll see the explosion replay over and over and over
