Hi!
In the Gurknukem example, I'm having trouble understanding how the player is spawned using the utiLiti.
I'm guessing it's all done in the background, but:

• 1. How does the program know which sprite to use?
• 2. Are there any more naming conventions, for creatures, than "-idle-" and "-walk-"?
• 3. Is it possible, with the method used in Gurknukem, to spawn different entities at different times with the same spawner?

CalvinMT In the Gurk Nukem example, all we provide on the map is a general purpose ~~Spawnpoint with the name ****~~enter****. This Spawnpoint is then later on used in code with its only purpose being to provide the position where something will be spawned. In the ~~~~GurkNukemLogic class, you can find this code:
~~```java~~// add default game logic for when a level was loaded Game.world().addLoadedListener(e -> { // spawn the player instance on the spawn point with the name "enter" Spawnpoint enter = e.getSpawnpoint("enter"); if (enter != null) { enter.spawn(Player.instance()); } });```` You can certainly use the same ~~~~Spawnpoint to add different ~~~~Entities at different times other than when the map was loaded. One way would be to implement the generic ~~~~EntitySpawner and provide it with the ~~~~Spawnpoints you want to use for this purpose. I'd recommend implementing some custom logic though that best suits your game because the ~~~~EntitySpawner itself is an old class that was used in the first version of **~~\*\*~~LITI-Stoneage Brawl\*\*** and hasn't seen any rework or generalization since then. *>*1.How does the program know which sprite to use? The engine knows that because in the example project, we've specified the ~~~~spritePrefix in the constructor of the ~~~~Player class.

There is one more default naming convention regarding the "death"-sprite (which is rendered if the ~~Creature is on ~~0 health). By default this is ~~-dead but it's also possible to provide multiple (different) "death"-sprites for a certain creature by specifying additional suffixes via ~~AnimationInfoannotation like so:```java@AnimationInfo(deathAnimations = { "dead", "dead1", "dead2", "dead3" })
public class Player extends Creature {
...````

Thank you very much!
Exactly what I wanted.
