Ok, I'll explain it here then...Mr. Sin Costan honestly do not really understand what he had seen in the .cs file
First off, you need your projectile json file (a given...). So I'll just use the example from the zip as the example.
Code:
{
"displayName": "Flame Blast",
"size": [8, 42],
"scale": 1,
"aiStyle": 0, //Gonna use this for a custom AI (since aiStyle 0 does nothing)
"timeLeft": 180,
"friendly": true,
"hostile": false,
"tileCollide": true,
"ignoreWater": false,
"frameCount": 3 //How many frames are there in the image, in this case it is 3 images
}Now we need our .cs file, FlameBlast.cs.
Code:
using System;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using TAPI;
using Terraria;
namespace MPT.Projectiles
{
public class FlameBlast : ModProjectile
{
public override void AI()
{
projectile.light = 5f; //Makes the projectile light
projectile.rotation = (float)Math.Atan2((double)projectile.velocity.Y, (double)projectile.velocity.X) + 1.57f; //Makes sure the projectile rotates so it is pointing at where you are shooting.
if(projectile.frameCounter < 20) //If the frame's counter is less than 20.
{
projectile.frame = 2; //Set it to the 3rd frame, since the frames go from 0 to 2.
if(projectile.damage <= 100) //Increases the projectile damage if it is less than or equal to 100
projectile.damage += 1;
else
projectile.damage = 100;
projectile.velocity.Y *= 1.01f; //increases the velocity by 1.01 times.
projectile.velocity.X *= 1.01f;
}
else if(projectile.frameCounter >= 20 && projectile.frameCounter < 50) //If the projectile's frame counter greater than or equal to 20 and less than 50
{
projectile.frame = 1; //Set the frame to the second frame
if(projectile.damage <= 100) //Increase the damage again
projectile.damage += 2;
else
projectile.damage = 100;
projectile.velocity.Y *= 1.02f; //Increase velocity even further
projectile.velocity.X *= 1.02f;
int DustID1 = Dust.NewDust(new Vector2(projectile.position.X, projectile.position.Y + 2f), projectile.width/2 + 4, projectile.height/2 + 4, 64, projectile.velocity.X * 0.2f, projectile.velocity.Y * 0.2f, 120, default(Color), 0.75f); //Add Dust to it too
Main.dust[DustID1].noGravity = true;
}
else //If the frame counter is something other than the two statements
{
projectile.frame = 0; //Set the frame to the first frame
if(projectile.damage <= 100) //Increase damage even further
projectile.damage += 3;
else
projectile.damage = 100;
projectile.velocity.Y *= 1.03f; //Increase speed even further
projectile.velocity.X *= 1.03f;
int DustID2 = Dust.NewDust(new Vector2(projectile.position.X, projectile.position.Y + 2f), projectile.width + 4, projectile.height + 4, 64, projectile.velocity.X * 0.2f, projectile.velocity.Y * 0.2f, 120, default(Color), 0.75f); //Add dust
Main.dust[DustID2].noGravity = true;
}
projectile.frameCounter++; //A seperate counter used for animation.
}
}
}So to top it all off, all you need to know from this example is that you need one property in the json file and about 2 properties in your cs file.
Code:
In the .json file
- "frameCount": int frameNumber, //How many frames are there in your texture
in the .cs file
- frame = int frameNumber; //Select the certain frame to show, goes from 0 to the frameCount minus 1 (0, frameCount - 1)
- int frameCounter; //The counter to help you animate. (like a stop watch)And here is one last example, only with the AI() hook though. Let's pretend I already did all the JSON file, with a frameCount of 4 this time and have it animate infinitely.
Code:
public override void AI()
[
projectile.frameCounter++; //Make the counter go up, just remember that each time it goes through the AI hook, it is 1/60 of a second, so you are counting by 1/60 of a second.
if(projectile.frameCounter < 10) //If the counter is less than 10
{
projectile.frame = 0; //Set it to the first frame
}
else if (projectile.frameCounter >= 10 && projectile.frameCounter < 20) //If the frameCounter is greater than or equal to 10 and less than 20...
{
projectile.frame = 1; //Set it to the second frame
}
else if (projectile.frameCounter >= 20 && projectile.frameCounter < 30) //If the frameCounter is greater than or equal to 20 and less than 30....
{
projectile.frame = 2; //Set it to the third frame
}
else if (projectile.frameCounter >= 30 && projectile.frameCounter < 40) //If the frameCounter is greater than or equal to 30 and less than 40...
{
projectile.frame = 3; //Set it to the fourth frame
}
else //Let's just say this assumes that the frameCounter is greater than or equal to 40.
{
projectile.frame = 0; //Reset it to the first frame
projectile.frameCounter = 0; //Reset the counter so it goes back to the beginning
}
}
