I've been messing with missiles and missile movers. It's all going fine except for one issue that's arisen: When i'm creating a linear missile (with a point destination and a search area effect to detect for collision) the missile will occasionally go straight through a unit instead of colliding. This usually happens at a certain threshold of speed, with a persistent calling the search area every .01 seconds a missile moving at a max speed of 30 there will always be a "sweet distance" were the missile simply goes straight through instead of colliding with the unit.

If anyone has any idea on how to prevent this (or if I just say to hell with making missiles with the editor) i'd be much obliged.

I think the minimum period for persistent effects is 1/16=0.0625, all values below that are set to this value. The rest should be obvious: If the missile travels farther than the diameter of the search effect during a single period there will be areas the search doesn't reach.

If you really need an insanely fast missile I suggest you go the Colossus route: use periodic offsets to define the splash line and make the missile purely cosmetic. If your missile is only supposed to hit 1 target you can use validators and dummy buffs to prevent further searches from executing, or possibly a Destroy Persistent effect (which I don't know how to use). Keep in mind this only works for predefined trajectories, the "missile" can't home in on a target unit.

@PhiSC2: Go

You should apply a buff to teh missile with a low period (can have very low, like 0.0001 or 0.00002 i think) and have it apply the search effect. Wht happens is the search effect doesnt happen too often and it always does not happen at the same distances (obviously).

Like I said, there is a hardcoded limit for period length. I'm not sure it's as big as 1/16 but it it a fundamental limit to missile speeds if you want proper collision detection.
