Hello In my multiplayer game you can jump, but i have a problem.

only the host or "-cl -sv" player is jumping. the clients won't
and whenever the host jumps the clients do too.

what could be the problem?

1. Every client's player must be created on local machine.
2. Using (key_*) or (on_* = *) ?

The problem is that the function/action that checks if the jump key is pressed, and then jumps is running on the server. If you use ent_create, the function you pass is executed on the server, even if you used ent_create on the client.

What you want to do is something like this:
Code:

---

client:
player = ent_create(..)
playerAction();

action playerAction()
{
   while(1)
   {
      if(key_space) {player.z += ..} // jump when space is pressed
      wait(1);
   }
}

---

thank you, i thought i did that.

The Walking & running works, its just when i try to add a new movement the client seems to not be able to do it and copy the host,

this is my handle gravity function that is called in a while loop in the player.mdl's action.

FUNCTION handle_gravity()
{
trace_mode = ignore_me+ignore_passable+use_box;
result = trace(vector(my.x,my.y,my.z - my.z_offset),vector(my.x,my.y,my.z - 4000));
IF (result < 3) //Result is the distance from the player's feet to the ground, if it is below 0 then it means the trace was inside a
{ //block and result returns a negative value,
IF (my.jumping_mode == 0) {
my.force2_z = -1 * result;
IF (key_space == 0 && space_press == 1) { space_press = 0; }
IF (key_space == 1 && space_press == 0 && my.movement_mode == 0 && my.animblend >= stand && my.animblend != jump &&
my.animblend != fall) {
space_press = 1;
my.jumping_mode = 1;
my.force2_z = 25;
my.blendframe = jump;
my.animate2 = 0;
my.animblend = blend;
}
}
IF (my.jumping_mode == 2 || my.jumping_mode == 3) { my.jumping_mode = 0; }
} ELSE {
IF (my.jumping_mode == 2) {
IF (result > 120) {
my.animate = 60;
my.jumping_mode = 3;
} ELSE {
my.jumping_mode = 0;
}
}
IF (my.jumping_mode == 3 && result <= 120) { my.jumping_mode = 0; }
IF (my.jumping_mode == 0 && my.movement_mode == 0) {
IF (result > 120 && my.animblend >= stand && my.animblend != jump && my.animblend != fall) {
my.jumping_mode = 3;
my.blendframe = fall;
my.animate2 = 0;
my.animblend = blend;
}
}
my.force2_z -= 6 * time;
my.force2_z = max(-30,my.force2_z);
}
my.velocity_z += (time * my.force2_z) - (min(time*0.7,1) * my.velocity_z);
my.force_z = my.velocity_z * time;
}


does this help?

No, you should look at the structure of the code I posted. The actuall contents don't really matter.

The problem is not in the function itself, but in the fact that it is running on the server, when you want to run it on the client. So create your player on the client, store its pointer in the predefined player pointer, and use that pointer in a function you call from the client.

I think I understand, i've changed all of the my.somethings into player.somethings
but the client still can't jump i'm sorry there must be something i'm missing,

i cant figure out why somethings work and somethings don't

how do i call from the client do you mean use the player pointer ?

How are you creating your player entity?

It is important that:
-It is created on the client (will automatically be created on all other connected systems, but you must call ent_create from the client).
-You understand that the action you pass as parameter to ent_create will run on the server. This means you shouldn't put your jumping code in there.
-Store the player pointer on the client: player = ent_create(..);
-Right after that, do a normal function call: playerAction(); (subsitute with you player action name) In this function, you should use the player pointer and not me/my. I think this is the thing you're still missing.
