 Re: Lua based map objects, help! (BW related) The gravity causes a constant acceleration of 20 m/s^2. So in a frame the change of velocity would be 20 m/s^2 * time of frame in seconds aka deltatime.

Oh and I think the hard-code for gravity would be essentially what you guys are talking about: constant acceleration downwards, which, in a physics context, it is; so constant acceleration upwards should be fine... except if your actor was heavy enough it could end up being really buggy... Here you go: Code: actor.Vel.Y = actor.Vel.Y + (20 * 0.016667)
Should double gravity.

Re: Lua based map objects, help! (BW related) Except WEIGHT does not affect GRAVITY jesus CHRIST.

Re: Lua based map objects, help! (BW related) Actually it does. The acceleration is the same, but the higher your mass is the bigger the force caused by gravity is.

Re: Lua based map objects, help! (BW related) oh wow more newtons exerted how handy. they should still be able to walk, things will just splatter, or at least take impulsedamage much more easily. it would basically be a no-jet no-prone (unless you were careful) area for any heavy actors, and probably light actors too.

Re: Lua based map objects, help! (BW related) Some help needed again!
How would one change the velocity to negative or make it fly in a reverse direction it was coming if a particle/item entered hit a certain area?
So basically I'm talking about a reverse field, particles and items that try to fly through it, are sent to fly in the opposite direction where they came from.
Pretty much how to change an objects velocity to negative with Lua code?
Another thing is proximity mine. Its fairly simple, but I dont know how would the detonation work. Is there a variable to make the objects gib itself?Because thats only what I need.
The mine itself would most likely be either a pinned MOSRotating or a pinned AEmitter (emitter could give a small effect showing the mine is active by blinking red.)

Re: Lua based map objects, help! (BW related) Code: for reverse in MovableMan.Objects do
reverse.Vel.X = reverse.Vel.X * -1
reverse.Vel.Y = reverse.Vel.Y * -1
end should do it. and also should gib the object should it not?

end But wouldn't that do it every iteration? I think you'd either have to make something to combat that or add a variable to check if it's been done... or maybe it'd immediately exit the area... hmm...

Re: Lua based map objects, help! (BW related) Heres the code for the Plasma Chaser, a grenade that sends out 6 Emitters that are supposed to chase actors. The grenade works normally, but the charges dont chase anyone. Also it doesnt matter if it would chase the use, its even better that way. Code: function Create(self)
end
function Destroy(self)
end
function Update(self)
for actor in MovableMan.Actors do
local diff = math.sqrt(math.pow((actor.Pos.X-self.Pos.X),2) + math.pow((actor.Pos.Y - self.Pos.Y),2))
if diff < 30 then
diff = 30
end
if diff < 600 then
local diffx = actor.Pos.X - self.Pos.X
local diffy = actor.Pos.Y - self.Pos.Y
local ang2 = math.atan2(self.Vel.Y , self.Vel.X)
local ang = math.atan2(diffy , diffx)
if math.abs(ang - ang2) < 0.8 then
self.Vel.Y = -(actor.Vel.Y - (50 / diff * math.sin(ang)))
self.Vel.X = -(actor.Vel.X - (100 / diff * math.cos(ang)))
end
end
end
end And just incase, I'll post the emitter code itself incase you might find something interesting from it. Code: AddEffect = AEmitter
PresetName = Plasma Chaser
Mass = 50
LifeTime = 7000
OrientToVel = 0.9
GlobalAccScalar = 0
RestThreshold = -500
HitsMOs = 0

GibImpulseLimit = 3000
GibSound = Sound
AddSample = ContentFile
Path = BW.rte/Sounds/ShockBallExplosion.wav Then the next thing is the repeller field generator. Its supposed to accelerate particles away from the field. It needs to affect MOPixels, MOSParticles, MOSRotatings, AEmitters and TDE's. Basicly particles and items. Not actors. Code: function Create(self)
end
function Destroy(self)
end
function Update(self)
for actor in MovableMan.Particles do
if (actor.ClassName == "MOPixel") and (actor.HitsMOs == 1) and ( not(actor.PresetName == "Mercenary Jet Particle 1")) and ( not(actor.PresetName == "Mercenary Jet Particle 2")) and ( not(actor.PresetName == "Mercenary Jet Particle 3")) then
local diff = math.sqrt(math.pow((actor.Pos.X-self.Pos.X),2) + math.pow((actor.Pos.Y - self.Pos.Y),2))
if diff < 40 then -- the smaller the value the sharper the bullets turn when they are close
diff = 40
end
if diff < 200 then --maximum range
local gravitymultiplier = 25 -- use this to adjust gravity to a fitting value
local diffx = actor.Pos.X - self.Pos.X
local diffy = actor.Pos.Y - self.Pos.Y
local ang = math.atan2(diffy,diffx)
actor.Vel.Y = -(actor.Vel.Y - ((gravitymultiplier / math.pow(diff,2)) * math.sin(ang)))
actor.Vel.X = -(actor.Vel.X - ((gravitymultiplier / math.pow(diff,2)) * math.cos(ang)))
end
end
end
end

end should do it. and also should gib the object should it not? Perfect! Both of these worked! The proxy mine works like a charm!  The other one however... all the guns are using "FireIgnoreThis = 1".  Looks like I could try enabling those. Are you guys ok on that your own gun can blow your arm off? Its pretty easy to die from enemy fire anyways, so this is a pretty hard choice to make. Rocket launchers ofcourse work like they would if you shoot them at your feet.

Re: Lua based map objects, help! (BW related) It's your decision, but I'm fine with being able to shoot myself with a weapon, just as long as in normal firing your arms don't fall off randomly. But of course you'd never be as unprofessional as to do that now would you Numgun? =)

I usually place the muzzleoffset a couple pixels forward where the actual barrel is and then adjust the flash with that. I'm just thinking if youre moving too fast or youre rolling barrels which you'll be doing suprisingly often in a deathmatch you might accidently shoot at your foot.
