    if (!is_valid_ent(iEntityID))

    console_print(iPlayerID, "[Test2] find_ent_by_class: %d", find_ent_by_class(-1, "testEntity2"));
} 


Output:

PHP Code:

test1
[Test1] cs_find_ent_by_class: 0
[Test1] find_ent_by_class: 37
test2
[Test2] cs_find_ent_by_class: 0
[Test2] find_ent_by_class: 38 


cs_find_ent_by_class should return the entity index on test1

I did something wrong or this is a bug?

I was going to answer soon.

Your issue is that it's the expected behavior from game. The hashtable code in game is working based on engine classname.

When you create an entity with cs_create_entity, a new hash is added in the table based on the classname you passed, here info_target.
Once you modify the classname, and you're using cs_find_ent_by_class, CS tries first to compute hash from given classname to see if it exists in table, and that's why it fails because hash was not saved from testEntity1.

Well, after discussing this with Nextra, considering it's useful and for consistency, it would be okay to add a new native to set a classname and updating hash. CS doesn't offer a way to update directly a hash so this will do: removing hash -> updating classname -> add new hash.

Right now, we are stucked to find proper native name \o/.

Maybe with

PHP Code:

cs_create_entity(szClass[], szClassName[] = "") 


or

PHP Code:

cs_set_entity_classname(iEntityID, szClassName[])
