[JASS] Bouncing Wisp, lol : D

[Nestharus]

I made this while working on a system for testing purposes and found it fun to watch = ).

You need the latest vJASS to run this. You can just paste it into a random map and hit save/test and it'll run : P

And here is 3D targeting methinks. If anyone wants to check over my math, go for it : D. I winged it, lol (Never done 3D vectors before, just used mah logic)

set yawRad = Atan2(targetY - yK, targetX - xK)
set yawK = yawRad*bj_RADTODEG
set pitchX = SquareRoot(Pow(targetX-xK, 2)+Pow(targetY-yK, 2))
set pitchY = targetZ-zK
set pitchRad = Atan2(pitchY, pitchX)
set pitchK = pitchRad*bj_RADTODEG
                        
set translationX = MOVE_INTERVAL*speedK*Sin(yawRad)*Cos(pitchRad)
set translationY = MOVE_INTERVAL*speedK*Cos(yawRad)*Cos(pitchRad)
set translationZ = MOVE_INTERVAL*speedK*Sin(pitchRad)

Next I gotta do magnetism, elasticity, friction, precise collision, and gravity i think? : O

 

[Darkt3mpl3r]

Really cool, but no one is gonna test it, unless you post us a testmap.

 

[PurgeandFire]

Cool stuff. Here is a test map with it.

 

[Darkt3mpl3r]

Pretty basic stuff seen 3 years ago. You're bit late with your submission. Check out anitarf
's vector system, shows bouncing wisps with unit collision....

profet is also creating a pretty nice system, check his out!

 

[Nestharus]

I know it's pretty basic ^.^

Like I said, was just a fun little thing i whipped up while designing a system ^.^

Wanting to do stuff like elasticity, gravity, magnetism, friction, and precise collision ; ). I'm planning so that you can have like things riding objects and so on.

This is what I've imagined for the longest time-
A flying city with moving floors (imagine linked platforms moving in different directions, like column 1 goes up and column 2 goes down, and imagine that the pattern continues all across)

Units being able to walk all over while being carried like normal

A hallway with holes in the floor (floor still moving)

Canons on either side firing rockets into the air with slight homing

Flying monsters (imagine regular 3D) with swords and magic (warriors land and fight and lift off and wizards cast)

A hero with a gun providing support on a platform
A lead warrior leading the way across
A priest healing people where the spell effectiveness is based on the ability of the priest to outline a line with a mouse
Platforms being made up of many smaller platforms, so as a piece is damaged enough, it'll fall off like debris coming off of a building


Honestly, that scenario would be so fun to play!! That is my dream, to make that ; D.

Ofc I'd want different projectiles to have gravity/charges/magnetism/elasticity so you could have absolutely wild spells.

Also imagine jumping up and down on a highly elastic floor or walking across these platforms with almost no friction? Or gliding around on a rocket pack : O.

I think it all begins with a powerful vector and spawn system (spawning so that effects can be shared across, like rocket attacks on canons, plus so these effects can be generated in patterns with ease, like a huge ball of fire made up of many units that eventually explodes (easy with adv spawning+adv vectors)).

I want grim001 to release his physics engine; though I doubt he has found the motivation to finish it.
