Help, i tried to use
public virtual bool CanExplode(int i, int j)
but it wont work. I tried to return false .
Click to expand...
you need
to tell us
what you are doing

public override bool CanExplode(int i, int j) goes in your modtile or globaltile, whatever you are using it for

make sure those virtuals are overrides
 
If I'm not able to deny a player's picking up, I come up with a rounded way to do this.
But once again met with some problems. It's about NewItem. Item generated by this, if using player's position, will be picked instantly by the player. I noticed that there is this bool NoGrabDelay, and whatever I set it to true or false, there is no delay. The item will be picked up instantly anyways.
I dunno whether this is because it ain't working. But how to generate an item, in the way like how mobs drop items, or just grant some seconds before it can be picked up? Since NoGrabDelay ain't working, anything else can I do?
Code: 
Item.NewItem((int)player.position.X, (int)player.position.Y, player.width, player.height, mod.ItemType("IchorKnifeOnPickup"), item.stack, false, 0, false, false);

This is because of how the projectile is drawn. If you want it to draw along its origin correctly, use the following code on your ModProjectile in the PreDraw function:
Code: 
Texture2D texture = Main.projectileTexture[projectile.type];
Vector2 origin = new Vector2((float)texture.Width * 0.5f, (float)(texture.Height / Main.projFrames[projectile.type]) * 0.5f);
SpriteEffects effect = projectile.spriteDirection == -1 ? SpriteEffects.FlipHorizontally : SpriteEffects.None;
Main.spriteBatch.Draw(texture, projectile.Center - Main.screenPosition, new Rectangle?(Utils.Frame(texture, 1, Main.projFrames[projectile.type], 0, projectile.frame)), lightColor * projectile.Opacity, projectile.rotation, origin, projectile.scale, effect, 0);
return false;

Nope, because i figured it out. Thanks anyway

On your ModPlayer class, create three variables and use them as follows:
Code: 
public bool bubbleArmor;
public bool bubbleActive;
public int bubbleTimer;

public override void ResetEffects()
{
    this.bubbleArmor = false;
    this.bubbleActive = false;
}

public override void PostUpdateEquips()
{
    if(this.bubbleArmor)
    {
        if(player.velocity == Vector2.Zero)
        {
            if(this.bubbleTimer++ >= 120) // 2 second cooldown
            {
                this.bubbleActive = true;
            }
        }
        else
        {
            this.bubbleTimer = 0;
            this.bubbleActive = false;
        }
    }
    else
    {
        this.bubbleTimer = 0;
        this.bubbleActive = false;
    }
}
public override
Now all you want to do when you update your set is setting bubbleArmor to true.
Also don't forget to use the PreHurt hook to modify the damage done to the player if bubbleActive is true.

That is because the drawing is now done differently, as the projectile is rotating around its origin.

                    {
                        this.bubbleActive = true;
                    }
                }

Do I put the prehurt in the bubble or the armour code?
Click to expand...
First of all, it should not be 'bubble code'. I advice you to only use one ModPlayer class instance for every mod you make, since usage of more might result in lag.
Second, the PreHurt should be one the ModPlayer class. If you followed the link I gave you, you would have seen the method was part of that class.

Hmmm, it might be with some tweaking, but not really sure what a good way would be atm.

my fault on the first one, it needs to be modPlayer.bubbleArmor = true; right?

Uhm...
In the Armor set update, you'll want to get your ModPlayer class instance from the given player and set the bubbleArmor boolean that way. There is no bubbleArmor variable in your ModItem now, is there?
And in the PreHurt function, return true.

Hang on, try the following draw line instead:
Code: 
Main.spriteBatch.Draw(texture, (projectile.position - origin) - Main.screenPosition, new Rectangle?(Utils.Frame(texture, 1, Main.projFrames[projectile.type], 0, projectile.frame)), lightColor * projectile.Opacity, projectile.rotation, origin, projectile.scale, effect, 0);
