Can someone show me how to:
1) Hook when items are spawned
2) On spawn of certain items I would like to keep them from spawning.

Something like

PHP Code:

OnEntityCreated(int entity, const char[] classname)
{
   if (strcmp(classname, "weapon_rifle")==0) 
   // kiil entity or keep it from spawning….
}

Depending on what you want,

Some attributes are only available (updated) on SDKHook "OnSpawnPost"
other stuff (like skin or owner) usually needs to wait for a frame (RequestFrame) to have the value updated. (after SpawnPost)
then you just have to kill the entity (KillEntity) or AcceptEntityInput Kill


Just a note, using weapon_rifle as example,

Some entities classname are not just "weapon_rifle" but "weapon_spawn" (then you need the weaponID) or "weapon_rifle_spawn" instead (may have other
variation aswell, eg. weapon_melee / weapon_item_spawn )

You might take a look

PHP Code: public void OnEntityCreated(int entity, const char[] classname) {     if( strcmp(classname "molotov_projectile") == 0 )     {         SDKHook(entity, SDKHook_SpawnPost, SpawnPost);     } } void SpawnPost(int entity) {     // Validate     if( !IsValidEntity(entity) ) return;     // Model valid now     char sModel[64];     GetEntPropString(entity, Prop_Data, "m_ModelName", sModel, sizeof(sModel)));     // Depending on entity, velocity might not be valid until the next frame     RequestFrame(nextFrame, EntIndexToEntRef(entity)); // The 2nd argument to pass variables into the callback is optional, in this example we're using it. } void nextFrame(int entity) {     // Validate     if( (entity = EntRefToEntIndex(entity)) != INVALID_ENT_REFERENCE )     {         // Now velocity data is correct         float vVel[3];         GetEntPropVector(entity, Prop_Send, "m_vInitialVelocity", vVel);     } }

You'll want to hook SDKHook_SpawnPost from OnEntityCreated and RemoveEntity() in the SpawnPost, otherwise likely to cause a server crash.
