Events and Range?

[ad]

I have two questions. Is there any way to make it if an object gets within a certain amount of pixels of another object it will shoot an object at that object. Also is there a way to make an event happen even if the screen isn't on it.

The easiest way to make an object shoot at another is to set up a detection object. When the object to be shot at collides with the detection object, make the object shoot it by setting a flag on or whatever.

If the object has to shoot in an infinite number of directions (i.e. in a circular radius instead of strictly left/right, up/down, etc.), you will want to look into Fusion's trigonometry functions, specifically the ATan2 function, which will essentially allow you to pinpoint the angle at which to make your AI shoot the incoming object. The trig functions can also be used to detect the distance between the two objects without the need for a detection box.

As for making events happen if the screen isn't on it, you'll need to be specific. Are we talking about an event on a separate frame, or in the same frame but far away? Either way, one thing to do would be to trigger a variable, either global or otherwise, for that specific event and when the player gets to where that event is supposed to happen, trigger it.

For instance, let's say the variable is "everything is on fire." If you didn't set off the event that triggers it, the variable would be 0. If you did do that, though, set it to one, and then specify in the code what happens when "everything is on fire" = 0, and what happens when "everything is on fire" = 1. If you do this as a Global Variable/Event/Object, you can have it affect multiple frames, or you can keep it within one frame.

All you would need is some triginometry.
Work out what radius the other object needs to be from your object for it to be within range.
Use an extension called Advanced Direction Calculator. It should do what you want no worries.
