I don't know if I will be back to modding Terraria, but I have updated it for the latest tModLoader on the mod browser, I don't know if I will be updating the git or the zip file anytime soon.

Not really, the closest I've gotten to a lightning like projectile was a pretty crappy laser like projectile that just changed velocities at random to simulate "electricity".

thats actually pretty much what im looking for. Got any ideas on how to do it?

Well, you should start off with your laser projectile with whatever dust type you want (you can find out how to make a laser using dust from within the files in the zip). Afterwards you would then add towards that AI adjusting the velocity of the projectile like "projectile.velocity" sort of like this:

Code:

projectile.velocity.X += 4;
// projectile.velocity.X is the variable to adjust the projectile's ability to go left or right, it's counterpart being y
// += is a fancier way of doing projectile.velocity.X = projectile.velocity.X + 4;

You would use if/else statements to make it do more than just go in one direction, probably use a timer to do this. Let's just say it does a random number between 3 and 7, something like this (note: I haven't done this for a while so it probably won't work).

Code:

int timer = 0;
int ranVelocity = Main.rand.Next(-6, 6);
//Somehow seperate the call of these and this next stuff

if(timer < 0) //just create a new random number to decrement if it reaches 0
{
    timer = Main.rand.Next(3, 7); //random number generator for timer
    if(ranVelocity > 0)
       ranVelocity = Main.rand.Next(-6, 0);
   else
       ranVelocity = Main.rand.Next(0, 6);
}
timer--; //decrements the timer

That's pretty much the crappy version of lightning like projectile I could manage...

Thanks a ton for that, Il try to get that working now

Well it isn't too dificult depending on how you go about it, you can use my example of the Shadow Blood Veil accessory on my github.

https://github.com/Harrison-Jue/COFP

The files you want to look at are ShadowBloodVeil.cs in the items folder, ShadowBloodVeil.cs and it's other counterpart in the the projectiles folder, and MPlayer.cs in the main folder.

Marcin JOT.PE · Dec 27, 2016

Thanks for help. I got one more question i used your tut how to shoot at a npc how to detect if there is collision of not with tiles

G4M3R57 · Jan 27, 2017

Oh, you made Terraria cool one more time, Thanks!

Sin Costan · May 9, 2017

So after a long time, I decided to update my mod to the latest Terraria once again, so... uhh, yeah, have fun!

question! How can i make my weapon fire projectile but appears when my cursor is on it

What do you mean by that? Like the projectile is invisible when the mouse is not over it or do you mean something else?

yanssenklugh · May 17, 2017

i want something like your rainbow destruction where you make a projectile appear on your cursor.

yanssenklugh · May 17, 2017

But if you still don't get what I am saying, this is what I mean:
I want my weapon to spawn the projectile wherever my cursor is. But how do I do that?

Oh, you can see that in my Rainbow Devastation Vortex projectile. Here is what the AI for the projectile looks like...

Code:

Vector2 vector14;
vector14.X = (float)Main.mouseX + Main.screenPosition.X;
if (p.gravDir == 1f)
{
   vector14.Y = (float)Main.mouseY + Main.screenPosition.Y - (float)p.height;
}
else
{
   vector14.Y = Main.screenPosition.Y + (float)Main.screenHeight - (float)Main.mouseY;
}
projectile.position = new Vector2(vector14.X - projectile.width/2, vector14.Y + projectile.height/2);

This should set the projectile's position to the cursor's position. So you can either use this code and set it up so the projectile spawns directly at the cursor or just have it spawn and then have the AI automatically move it to the cursor after 1 tick.

Thanks! It now spawn on my cursor

Question, if I want the projectile go cursor after 120 ticks or more?

Add a timer with projecitle.ai[] and use the homing code in my tutorial to have it home towards a position instead of an NPC.

Okay so i wanted your boss so i went to your github and copied the code but made my own sprite (I will edit it soon though like the names) but when I build and reloaded it

Huh, I thought I updated the code in Github already, apparently I forgot to sync changes, should be synced now.
