eli0s I noticed a problem with the additive method. It makes the canvas area fade to whatever the colour of the eraser is. That's not good if I'm using a background of any kind.

eli0s I'll try that when I get back home.

Maybe it just takes a while for the trail to fade completely.

Ragevortex That would be awesome! However the line itself is a tiled background, same with the "Eraser" object that gets the trail effect to work, so unless I apply a shader effect to both it'll be difficult.

eli0s I think the remaining trail issue has to do with the opacity of the eraser value. I've gotten better results setting it to 10 instead of 1.

How does this look:

— Yeah, the example uses a sine wave at 2 second periods, just to show that it works.

eli0s I can see your point. I think it might work better if there was a trail effect or have more than one line displaying at a time. Just need to experiment with it.

That radar line idea sounded quite cool, so I thought I'd implement it and performance is incredible. The vision cone implementation I explained earlier used around 5% of the CPU on my desktop, which isn't much except that the radar method only uses less than 1%!

See for yourself!

Athough I'm thinking of if there is any way to improve the visibility of it, I was thinking of making it trail but that would add to drawing. :/

For me, it'll depend on my use of time. Saturday especially since I usually travel somewhere, and usually long distances.

So I have a game that uses turrets, and I want to use the line of sight object to detect players, and show the line of sight cone for the player to see. However I also want it to occlude to the walls like below:

This one was done by blending a light cone graphic with a canvas with rendered "shadows", which is very effective but very costly, especially if you are using multiple turrets.

Any ideas for a more simpler method? Probably one that actually uses the line of sight behaviour?

Optimisation: don't waste your time

If you saw the project files I'm using, optimization is pretty hard to ignore.

This shader is awesome! I've been looking for something like this for months. Is it okay for us to use it in our projects, with credit where it's due?

As an example situation:

Sometimes I use actions on objects that are pinned to other objects, and I've found two working methods:
• Use a for loop and perform the action on the condition that the pinnedUID property is equal to the pinned object's UID
• Use the Pick By Comparison to see if pinnedUID property is equal to the pinned object's UID

I've found the Pick events to be useful for a lot of situations like them, but I'm curious to know if these have much, if not any negative effect on performance.
