made a pic to show u what I mean.

You fire the projectile, and this projectile has a cog attached

Every pulse (of about 0.1 seconds) i need the projectile to "bend".

Now I will have a set of numbers to simulate a sine wave, but the sharpness of the sine wave will also be random.

I cant quite find the commands to change the getsenderref()'s vector.

Imagine the ancient drones from stargate, they fly as if they're an insect seeking out an enemy.

Hopefully you know what I mean.

the Commands I need is basically:

Change Vector ( x - (+ or -) flex * sinecount (simulate sine wave), y - (+ or -) flex * sinecount (simulate sine wave), z)

help and i will offer sweeties to all.

if(getThingFlags(source) & 0x8){
  do her}
elseif(getThingFlags(source) & 0x4){
  do other babe}
else{
  do a dude}

SetThingLook(GetSenderRef(), NormalizedVector);


Use "ThingPulse" to set the pulse. NormalizedVector is the vector direction you want the object to look at.

look at yes, but travel? no

I tried and it just makes the projectile spin.

I need these projectiles to actually CHANGE direction slightly every pulse, ya dig daddiio?

if(getThingFlags(source) & 0x8){
  do her}
elseif(getThingFlags(source) & 0x4){
  do other babe}
else{
  do a dude}

Have you already come up with an equation to generate the wiggling look vector?

If so, after you set the look vector of the projectile (on the line below SetThingLook() if possible) use:
SetThingVel(dummy, VectorScale(GetThingLVec(dummy), 5));
Where 5 is the speed you want the projectile to travel.

If not, search the forums for the sine functions and hopefully one of the sin/cos COG guys can help you get that junk working.

At worst you can probably fake the swerving calculations with a rotation of preset values to add to the thing's lookvector each pulse.

QM

it works!

I used :

Old Vector = GetThingVel (original direction of the projectile)

New Vector = VectorSet((Sine func)Rand(), (Sine func)Rand(), (Sine func)Rand())

combined Vector = VectorAdd(old vector, new vector)

SetThingVel (projectile, combined vector)


And the result is fantastic.

Imagine hundreds of purple glowing orbs flying out and darting around like insects.

God bless the power of cog

if(getThingFlags(source) & 0x8){
  do her}
elseif(getThingFlags(source) & 0x4){
  do other babe}
else{
  do a dude}

Giggedy.

Would you mind posting the exact code you used? I personally would love to be able to use a bending projectile.
