Changing player velocity

[arawra]

I want to be able to make players leap. I thought this would be the way to do so, but it doesn't have the desired result. A player's velocity doesn't seem to change at all.

Syntax: Select all

from events import Event

from mathlib import Vector

from players.entity import PlayerEntity
from players.helpers import *

@Event
def player_jump(ev):
    player = PlayerEntity(index_from_userid(ev.get_int('userid')))
    lunge(player)
    
def lunge(player):
    x_vel = player.velocity.x * 200
    y_vel = player.velocity.y * 200
    player.velocity = Vector(x_vel, y_vel, 200)

You need to use, player.teleport(None, None, velocity_cector) ti "apply" a velocity, those attributes are read only by the engine. You could also look at basevelocity but teleport is definitively better

Having weird problems,

Syntax: Select all

<Player>.teleport(None, None, Vector(0, 0, 0))

doesnt work but

Syntax: Select all

<Player>.teleport(origin, None, Vector(0, 0, 0)

works

[decompile]

Still having problems with that on CS:S Windows:
When I want to reset the players speed.

Syntax: Select all

<Player>.teleport(<Player>.origin, None, Vector())

or

Syntax: Select all

<Player>.teleport(None, None, Vector())

both doesnt work..

Well, that code works. It doesn't do what you want, that's different. When you use a null vector as velocity, you tells the function to apply nothing. In order to stop the motion of a player, you need to apply his current velocity reverted.[python]<Player>.teleport(None, None, player.velocity.negate())[/python]

Syntax: Select all

player.velocity.negate()

negates it in-place and returns nothing. It won't work that way.

Try this

Syntax: Select all

velocity = player.velocity    # Save shortcut value to a variable
velocity.negate()    # Multiply vector by -1
player.base_velocity = velocity    # Use base_velocity to apply velocity to a player

or this

Syntax: Select all

velocity = player.velocity    # Save shortcut value to a variable
velocity.negate()    # Multiply vector by -1
player.teleport(None, None, velocity)    # Use teleport to apply velocity to a player
