Homing missiled? how would you do it?

[kewlthis]

I want to create homing missile spell, that would chase the enemy. If it misses the target unit, it will slowly turn and start chasing the unit again.

I dont know if that explained it enought...But I was thinking whats the best way to do it. Should the angle of missile be changed and ordered to move some point. Or can it be some other way?

like in hungry felhounds or warlocks homing missile.

no. i want it to be able to miss and then chase enemy. so it can be evaded.

I know the map warlocks v0.81 has a spell called homing missiles. It does exactly that, i suggest you try to open the map and look at the code on how its done. I don't know if its protected or not but its worth a look.

Basically, periodically make the unit turn toward its target as opposed to moving straight at the target.

That is to say, in the latter case, you simply move the missile toward the target. It's guaranteed to hit.

But you want the former case, which basically just makes the missile move forward but you change its angle periodically to line up w/ the target. The more you change its angle, the better it homes.

Periodically, you:

1) Update its angle (may be a custom value or a variable linked to that unit)
2) Move it in that direction
3) Profit.

This makes it possible to evade the homing missile.

In addition to what soga said. you should keep an eye out on Element of Water's projectile system. It shoots a projectile that will hit whatever object it runs into first. Once he finishes that you could maybe use his system but addon to it to change the angle.

How is that possible to evade ? Didn't get it.
You should give it a velocity towards the target, then every now and then (not VERY fast) change it's facing angle a bit towards the target.
Just mess with the times between changing and the value that changes and you can get a nice looking homing thingy.

That's what I said...

Sounds simple, but i find it a bit hard to make it. I found felhounds map that has similar system.

Does it have to be that complicated as it seems from that? Well I quess i would first have to learn it myself (felhound system) to create a better one.

*edit* nvm...its simple enough. i suggest checking that map if you wana do homing missile thingys.
