[vJASS] Collision Ability

[pred1980]

Hi hivers,

i have an idea to make an ability which deactivates the collision of a hero for x seconds.. BUT the collision should only work for all allied computer controlled units but not for allied real player units. Is that possible?

Possible, but implausible. You might be able to do it for an individual unit but there are many issues to deal with.

Can u explain it pls....

You'll need to disable collision and then build your own pathfinding algorithm to override the existing one. Nestharus https://github.com/nestharus has built an A* (high performance) pathfinding algorithm in JASS but even that is too slow for viability. You'll need to severely limit the use cases or cut out features if you want any chance to do this.

I'd rank this in the top 10 most difficult class of problems in JASS.

ok - I forget that ^^

Just a hint:

You can use a modified permanent windwalk to disable unit collision checks, but leave the terrain pathing checks intact.
The Collision native bugs up the pathing; Windwalk on the other hand works flawless.

Simple thoughts about what you could make:

- Make a shift movement spell which let your hero shift through allied units in a specific direction but not through enemy units.

- Make the hero flying with a flying hight of 0.
-- Then you could take flying away if there is an enemy unit near the casting hero
-- or you could slightly knock back the hero from enemy units so that he or she can not fly over an enemy unit.

Give 'Ghost' to the hero, then periodically pick living ground (and that suffice your conditions) units around it (IsUnitInRangeXY considers collision size) and knock the hero away from those. You probably have only single heroes having activated the feature, so it's much more performant from their end.

Thx for your ideas.
