How to activate entities ??

[Prelauncher]

Ok. would be a bit easier if I could see your script but are you using this line for when the player pick up the key: SetEntityCallbackFunc(string& asName, string& asCallback);
Calls a function when the player interacts with a certain entity.
Callback syntax: void MyFunc(string &in asEntity, string &in type)
Type depends on entity type and includes: “OnPickup”, “Break”, “OnIgnite”, etc
