Making missle system more efficient

[kleinerhauck]

Hi there,
first time I need some backup on my trigger ;-)
I made a missle system for my map City of Terror II which is doing quite well.

But when there are many missles (like 50+) the game begins to stutter.
I work with GUI, used a 0.03s timer and there are no leaks.
(-> It stops stuttering when the missles are gone)

Basically I am looking for a way to make the collision-check as efficient as possible (and I don't want to use other systems that don't fit to my map).
And to do this, I tried checking the collision with destructibles only when the missle spawns for all destructibles within it's maximum flying range, instead of picking nearby destructibles in the 0.03s timer.

It works, but it produces even more stuttering (actually a short freeze of the game) if more than 5 missles spawn within 0.1 seconds.

So I'm asking myself is there a better way?
For example saving all the destructible positions in an array and looping through the whole array?
Or something else?
Maybe someone has experience with this. Thanks in advance for your help.

well, an easy way is to check to see if the terrain is pathable at the projectiles location, using

• Set Boolean = (Terrain pathing at Somelocation of type Walkability is off)

I didn't know this function yet, thanks.
This might indeed be alot faster, *trying*

€: This is really good, thx again.
If somebody else wants to use this, note that the function returns the wrong boolean value.
So this

• (Terrain pathing at Point of type Walkability is off)

actually returns false if the terrain is not walkable!

You should upload test map or ask spell mods for help, they can give you really advanced opinion about your code.

Look at Bribe's 2DKnockback and see how he detects it with abilities. That's a great way to do it in GUI.

Wow using Inferno is rly genious.. I'd never think of that.

I guess it doesn't rly matter which of the 2 ways you use unless you add pathing blockers later in game - then the terrain pathing function won't work and Bribe's method is better.

You can also use an item, moving it around although item's collision size is 16(?) and most units are larger than that. Second though, it's a fine to use it.
