I am trying to create a module like hs's pointdefence, but a bit more configurable (eg. Firing repels, bursts). I am looking at hs's pointdefence module, but I am confused about the x and y position, since pointdefence can be un-attached and made to follow the player. So can someone help me with creating a position packet for a turret? I should be able to take it from there.

where did you find the pd src?

What exactly are you trying to do? If you want it to fire something else, you can just change the weapon (look at addTurret).

@Cheeze: Someone asked for help on how to create a turret and dr brain gave him the source. Search the forum.

What I am trying to make is a fake player that attaches onto a ship and can fire guns, bombs, bursts, thors, and repels. I want to know how to make the fake attach to a player and rotate.

That's exactly what I wanted to know too... Dr. Brain kindly provided his pointdefense source as a reference, but it's intertwined with other Hyperspace modules and not meant to drop directly into ASSS. It's a bit over my head right now to try and implement something similar, even with his code as a guide. He claimed it was buggy as well, although it sure looks good in Hyperspace.

Also look at the funky/autoturret.c for a turret that automatically aims and fires L1 bombs (easy enough to change what it shoots). Wish I could figure out a way to detect projectile collision for it so I could kill it.

Soo... Can anyone tell me how to create the turret packets? First, what is the packet? Is it the C2SPosition struct, or is it something different?

I looked in the pd source, and I see that it sends a SimplePacket once when it attaches, but how do you tell it to rotate?

Probably make it send position packets?

Just a guess

Yeah, thats what PD looks like its doing, but what do I put for the X and Y values? Could I copy off of the attached player?

PD does this for xspeed and yspeed

Code: Show/Hide

int deltaTime = current_ticks() - data->pos.time;
int v_x = data->pos.xspeed;
int v_y = data->pos.yspeed;
int x = data->pos.x + deltaTime * v_x / 1000;
int y = data->pos.y + deltaTime * v_y / 1000;

data->pos is the owner's position packet.

so that's what it does, it gives the same x/y than the player... because when you detach the PD, it keeps following you

the + deltatime thing is just to put the turret a bit in front of the player (or right on him, if the last known data about the player is a bit old)

Ah, k. I'll just copy that.

I'll let you know if anything else goes wrong.
