Trigger Multiple Units

[RSK]

Hi,

In level flow I have made a simple flows that triggers visibility and animation for a single level unit, like a door for example. 

How do I trigger multiple units from the same trigger? Do I have to put in "level unit" nodes for each and all of them or can i group units together somehow? Something like 50 lights turning on at the same time

Best regards,

Rolf

This can be done in a multitude of ways.

If you are going to be triggering a large quantity of lights, the easiest way would be to set a global variable in your flow somewhere.  like a bool with the name "lights_active" and set it to false on start.  then whenever something is triggered that variable gets set to true.  Then in your lights unit flow, you could check that variable every frame and enable the lights when true.  This is not the most efficient way but would work fine in most cases and would work easily.

Another similar method with more control would be to set your lights every frame to a global value...  something like numeric glabla, "light_intensity" 0.  You can then set this variable in your level flow.  On each frame in your unit flow, just set the light(s) intensity to this global variable.  This would allow you to effectively dim all the lights in your scene.

For both of these examples you would want your light fixtures to contain the lights to be affected. This way the lights can be controlled from that units flow.  Typically this is how i deal with lights.  I make the model of my light fixture, add a light to that object and export it to stingray with the light included.  Because the light is part of the unit, i can just write the light control stuff into the unit and have a very easy time of it.

Hope this helps.

Feel free to inquire further if something does not make sense.

Thanks Paul for your suggestions - will have to play around with these solutions.

Can I use the same approach if I want different things to happen on a single trigger, like for example run a door animation, play a sound, fade in lights and move an object simultaniously?

If I understand your post correct both methods will have these units constantly checking/listening for a value. Will that not give performance issues or is that simply how to do it in game-making? As you might have guessed I have no experience with game engines...

The triggering events are quite efficient for dynamic game calls , and works well. for multiple stuff. It follows various paths of what you want. if things have to done simultaneously in succession or one by one in sequence. Then you can use sequence node to fire the other stuff with single trigger call. or you can control multiple stuff happening around in the scene. like dimming lights, doors closed, zombies spawning.  then as paul explained you can do this with set of global variables along with unit script data to update the scene, with the single trigger. For former approach following tutorial might be helpful.
