Get units/s

[decompile]

HeyGuys,

Just want to ask how you convert the velocity to units per second?

Like in ES you could use:

Syntax: Select all

vecmath.vector(525, 3500, 10).length()

Syntax: Select all

def playerVelocity(self):
    return PlayerEntity(self.index).velocity

and it seems like it has no .length() attribute and it only returns the vector.

Given the vector v(x, y, z), you can calculate its length this way:



I believe SP provides .get_length method for Vectors

Thank you, worked.

Syntax: Select all

return PlayerEntity(self.index).velocity.get_length()

Indeed:
https://github.com/Source-Python-Dev-Team/Source.Python/blob/master/src/core/modules/mathlib/mathlib_wrap.cpp#L139

Though we could (should?) change that to be a property named length.

What about __len__ method? Or is it too implicit?

[necavi]

__len__ is pretty explicitly for containers only. I don't see much benefit to doing len(vector) over vector.length, really.

How can I get the the units without z? So the actuall forward speed?

[iPlayer]

Use the first formula from the picture I posted

[satoon101]

To easily do that, you can always zero out the z value of the Vector:

Syntax: Select all

velocity = Player(index).velocity
velocity.z = 0
return velocity.length
