Hi,

I'm attempting to figure out what type of entities I should use in my map to have SourceMod react when a trigger is hit.

I have a trigger_multiple entity created in my map titled multiple1.

Here is my code:

PHP Code:

public OnEntityCreated(entity, const char[] classname)
{
    char entity_name[50];
    GetEntPropString(entity, Prop_Data, "m_iName", entity_name, sizeof(entity_name));
    
    LogMessage("Entity %d has been created.  Name: %s  Classname: %s", entity, entity_name, classname);
    
    if (StrContains(classname, "trigger"))
    {
        SDKHook(entity, SDKHook_StartTouch, OnEntityTouch);
    }
} 


Here is the output from the LogMessage above:

Mar 18 18:20:27: L 03/18/2020 - 18:20:27: [TriggerTouch2.smx] Entity 76 has been created. Name: Classname: trigger_multiple

You can see that the name is returning as blank. How can I fix this?

Try "m_ModelName".......

Thanks for the reply. Using m_ModelName:

PHP Code:

GetEntPropString(entity, Prop_Data, "m_ModelName", entity_name, sizeof(entity_name)); 


provides the same result.

Prop_Data and "m_iName" is correct to get the targetname. Are you sure it's set? Don't see why it wouldn't retrieve it. Which game?

I know this is just a test case, but instead of StrContains it's more efficient to use:

PHP Code:

if (strncmp(classname, "trigger", 7) ) 


to check the first 7 chars match "trigger" to detect all types of "trigger_*" ents.

Maybe use Stripper:Source to dump the maps properties and verify it's targetname in there. Doesn't make sense unless this is some uncommon game and "GetEntPropString" is broken on it but you would surely get errors saying so.

Forgot to mention... this is CSGO. Also, thanks for the tip with strncmp.

In regards to if the entity name is set... I know it is because I created it in hammer:



I'm having an issue getting Stripper:Source running on my test server but I'll try and confirm when I can get it running.

http://www.bailopan.net/stripper/snapshots/1.2/ grab the git129 version, I guess that should work.

I don't know if this is another issue with CSGO or what, sorry.

Maybe this can help you...

Entity properties are not yet available in OnEntityCreated, you need to wait until the entity is spawned.

Also,

should be:

if (-1 != StrContains(classname, "trigger"))

or better:

if (0 == strcmp(classname, "trigger_multiple"))

To match all "trigger" entities like OP was attempting. But since you know which trigger specifically I would match the whole classname in this case anyway.

This was most likely the problem. When using OnEntityCreated you have to wait for the properties to be valid so hook the entity with SDKHook_SpawnPost and it should work. Some things require RequestFrame within SpawnPost to delay it even more before getting valid properties but I've only noticed this is required for getting the velocity of a projectile. See the [TUT] I wrote for more details.
