interaction with 2d spotlight

I am trying to figure out a way to do 2d spotlights, that can be affected dynamically by sprites in the scene that move - dynamic shadow casting.

Adding to that I want to be able to use it as a condition when the player is overlapping a shadow or not- so I need to use the dynamic shadow as a colision.

Is this possible to do without external plugins?

I've been playing around with this (not got very far) but have a look at http://www.scirra.com/forum/another-waste-of-time_topic83212_post485669.html?KW=#485669 and it might give you some ideas.

Hi thank you for the reply!

You have one example capx file, which can not be opened in the current release version of construct (152).

Are you running a bleeding edge version?

Just the latest beta -

https://www.scirra.com/construct2/releases/r155

Actually, it shouldn't be too hard to open it in another version (if you don't feel like downloading >100MB because there is no update system for the software):

• unzip the .capx file with something like 7-zip in its own folder
• open the .caproj file with any text editing program (Notepad++ works nicely)
• find the line "<saved-with-version>XXXXX</saved-with-version>", where the X letters will be the version number
• change it to whatever version you have (for example r152 -> 15200)

For this, tell me what is "bleeding edge" supposed to mean.

Stiivais - thanks, I never knew you could do that.

Bleeding edge (or cutting edge) - "State of the art, the highest level of development, as of a device, technique, or scientific field"

is there a way to combine the CANVAS plugin with the LINE OF SIGHT behaviour?

Is there a way to visualize the LINE OF SIGHT behavior - make it look like a flashlight

I've been playing with the examples I pointed you at above - and am slowly getting closer...is this the sort of thing you are looking for ?

I want to use multiple torch lights for a stealth game mechanic, where you need to stay in the shadows- in the sense of a platforming game.

Currently there doesnt seem to be a simple solution to create a cone of light that can get affected partially by blocks.

It would be so amazing if someone writes a proper plugin for this. There are numerous dirty hacks. The canvas solution doesnt seem to allow for collision detection on the cone of light

Can you share with me the Line of sight hack to get this flashlight effect? I would much appreciate it.

Without a capx file I have no idea how you did it exactly

I've put it over in my waste of time post (link above)

this is fantastic! And in so few lines of code too! Well done. You should put it up as a tutorial.
