Connect two instance's imagepoints with a line

I can't figure out how to access both instances and imagepoints to then make a line that connects both.I'm trying to connect two raycast lines (variable size) on the "point" imagepoints to cast sort of a cone shape. It has to be instance specific so that multiple objects can cast that cone as well.

In this example I have 4 raycasts coming from an emitter with a specific range. The distance between the points varies when they collide with solids.

I tried creating variables to identify each instance and tried following Yann's example from this link: construct.net/forum/construct-2/how-do-i-18/check-distance-between-2-insta-43358

But still couldn't figure out how to do this

I know this is complex but if anyone could help me it would be hugely appreciated.

Here is my capx: dropbox.com/s/aw7susogmra8duq/distance2imagepoints.capx

Drag and drop the black box to move the raycasts.

I am not sure if i understood right but maybe this is what you are looking for:

Yeah, I also don't understand your question. If you are asking how to refer to two instances of the same object in one event, you can do this with IID, for example:

distance(Sprite(5).ImagePointX(1), Sprite(5).ImagePointY(1), Sprite(7).ImagePointX(1), Sprite(7).ImagePointY(1))

Where 5 and 7 are IIDs of two instances.

.

Another trick is to use a family. Create a family with this sprite and then you can pick 1 object instance and 1 family instance in the same event and access both instances separately.

That solves it! Thank you very much! It was just like what kriand showed! Sorry for the confusion I didn't know how to explain it very well.
