Shoots

[Schetti]

2 questions.
A: Can someone explain me a simple shoot script(for bullets like on era)

B:Why is shootarrow etc. clientside only?

[Chompy]

PHP Code:

// Will shoot a projectile in the direction of the player
//#CLIENTSIDE
function onCreated() {
  temp.startx = player.x+vecx(player.dir);
  temp.starty = player.y+vecy(player.dir);
  temp.startz = player.z;
  temp.angle = getangle(vecx(player.dir), vecy(player.dir));
  temp.zangle = 0;
  temp.power  = 0;
  temp.ani = "arrow"; // projectile ani
  temp.aniparam0 = 0;
  temp.aniparam1 = 0;
  // etc
  shoot(temp.startx, temp.starty, temp.startz, temp.angle, temp.zangle, temp.power, temp.ani, temp.aniparam0, temp.aniparam1); // etc with the aniparams
}

} 


May I suggest the following changes for the starting position:

PHP Code:

  temp.startx = player.x + 1.5 + vecx(player.dir);
  temp.starty = player.y + 2 + vecy(player.dir);

Because the coordinates I suggested are approximately the center of the player. If I recall correctly, that should work better with projectiles. Don't hurt me if it does not

A little bird told me that since projectiles use gani's they can be projected from the player's position(player.x,player.y) and not hit the player

Good to know ;P

More specifically, since shoot() uses a gani, and the gani's follow the same proportions as the player(size-wise), all you have to do is put the projectile in the gani in the center(like it should be anyways). Shoot() the projectile from player.x,player.y, and the projectile will visually originate from the center of the player.

Looking at this just brought something to my attention, is there vecz(), i know it seems pointless and most likely is, but just curious. o.O

No, because it would always return 0, seeing as in relation to player direction, you can only move in two planes.

[Schetti]

shoot(temp.startx, temp.starty, temp.startz, temp.angle, temp.zangle, temp.power, temp.ani, temp.aniparam0, temp.aniparam1);


with the numbers or just like written above?

[thatdwarf]

just like written above as long as those variables are defined
You can see in Chompy's script where those variables (temp.startx, temp.angle, etc) are given values.

You can very well just put all the numbers/math in the appropriate location in the shoot() function, but it's very messy, and considered bad practice to use "magic numbers", meaning numbers without clear meaning.

Defining the variables beforehand gives the code more readability ^_^
