Curt84328 Posted September 24, 2016 Share Posted September 24, 2016 I set an object variable for severa; trains (Camera). It shows in the EV with the correct value. I read the name of a loco with $_Trigger1._Name. I store that name in a global variable. Can I now read the name of the camera for that train, and tell the EV to activate that camera?

BahnLand Posted September 24, 2016 Share Posted September 24, 2016 Hello Curt, yes. See the attached example. Referring variable contents.mbp Click to the switch to start and stop the train. Many greetings BahnLand Link to comment Share on other sites More sharing options...
trevor Posted September 24, 2016 Share Posted September 24, 2016 Why not just use $(_Trigger1.Camera) ? Link to comment Share on other sites More sharing options...
BahnLand Posted September 24, 2016 Share Posted September 24, 2016 (edited) Hello Trevor, you are quite right. Even you can avoid the parantheses here. But the aim of the example above was to explain how different variations of global and object variables may be used to buffer and later evaluate some object properties. See here the optimized example (without "buffer variables"). Using loco object variables directly.mbp Many greetings BahnLand Edited September 24, 2016 by BahnLand Link to comment Share on other sites More sharing options...

However, it is generally bad practice to use global variables if you do not have to. On a simple layout you might get away with it, but the more things you have happening the more opportunity there is for multiple objects to be referencing the same variable at the same time with unpredictable results.
