I have been playing with pev_velocity and i noticed the that code below has an unsual bug:

#include <amxmodx>
#include <fakemeta>
#include <hamsandwich>

public plugin_init()
{
    register_plugin("[ZP] Jetpack", "1.0", "@bdul!")
    
    RegisterHam(Ham_ObjectCaps, "player", "fw_PlayerUseAttempt", 1)
}

public fw_PlayerUseAttempt(id)
{
    static Float:velocity[3]
    pev(id, pev_velocity, velocity)
    
    velocity[2] += 40
    set_pev(id, pev_velocity, velocity)
    client_print(id, print_chat, "Your Velocity: %.1f %.1f %.1f ", velocity[0], velocity[1], velocity[2])
}

Now, this is a type of a Jetpack i have been working on, the problem is that when i press the use key, 40 units is added to my z velocity but it doesnt work and i remain on ground (instead of being lifted).

Also, the reading i m getting from client_print clearly shows that 40.0 units is being added to my velocity :S

However when i jump and then press the use key immidietaly (while i am in air) i get lifted and the code starts to work. The problem is why cant i get lifted from ground and why does it only works while i m in air ?

First

velocity[2] += 40

=>

velocity[2] += 40.0

I think, it's gravity
You set a constant speed. But you should give an acceleration. For example, add z speed with some interval.
When you in jump, you have intial vertical speed.

Look at my bullet pogo plugin, it does something similar to what youre trying.

I kept my use button continuosly pressed, so that 40 units was added continuosly to my velocity

Bugsy, i looked into your plugin and this is how you set the velocity:

pev( Invoker , pev_velocity , fVelocity );
fVelocity[ 2 ] = get_pcvar_float( g_pStrength );
set_pev( Invoker , pev_velocity , fVelocity );

But wont it set the z velocity to a continous value ? I want the z value to be added to the current one so that if you are falling you will sort of get an upwards push like a real jetpack
Edit: i tried your code and it also haves the same problem, also, your code doesnt accelerates you upwards instead it keeps in a constant z velocity (like i suspected it to do)

I dont get it what is the problem exactly !
