LoS in Flash

[Eliyahu]

Currently, what is the best way to determine if an enemy can see the player, in a flash-friendly way. I'd do it with fastloops normally moving a detector object and if it hits an obstacle, stop the loop, if the loop reaches an end, fire a bullet.

Overall I want my enemies to shoot when the player is in their LoS. And I don't want flash to lag. Solution?

Thanks!

You have a few options...

Rotating/Scaling active (Slowdown! oh noez!)
Fastlooping as mentioned (Slowdown! oh noez! can be reduced with bigger step and spaced test time (eg 8 px line every second rather than every frame)
Shooting an object in realtime (Slow reaction! oh noez! but no slowdown...)

Custom extension?

Hi rickyRambo I also am having trouble with a line of sight flash friendly.

I choose to use the LOS widget, it works fine within the mfa, however i believe using this within flash has caused slowdown.

Altough i do not see why it would be?

Willow I'm working on an LOS extension that will work with tile-based maps. It will check for collisions on the tiles, and that is all. So as long as you don't need to be able to test looking through actives and such with funky shapes, and moving objects, it'll work.

PM me if you're interested in this.

I was messing around with a stealth game. The two ways I kinda did it was.

Have a LOS active thats invisable by follows the baddie around. I did have some weird things happen though.

Secondly i had the baddie shooting a invisable object every second. That worked better, although still not perfect.

My solution was to make an extension that does this:

Arrows move the black dot, the string tells you if there is a clear path from your mouse to the black dot. The extension can take different tilesizes, different step sizes for the testing (my example is set to 1, but it could be set to 5 pixels for example if precision is only necessary to that degree) and you can just set if a tile is an obstacle or not.

The only condition is, Is Path Clear from (x1,y1) to (x2,y2)?

If you want to beta test it or something, PM me.
