Sometimes when I shoot a bullet and it hits a glass block, it acts like it hits ground, or sometimes it traspasses it. 

I have coded the bullet to break vanilla glass and spawn particles when it hits IRON material blocks, which does,.... sometimes...

Could it be that the bullet's position is not updating in time before it hits?

White cloud is the ground impact event and the crit particles are the iron material effect(thats armored glass)

Yep, it has something to do with the bullet speed, I made the bullet a lot slower and its reacting always as expected when it hits glass etc etc, but I obviously cant make the bullet go slow, it wouldnt feel like a real gun anymore.... Is there a way to make the game update the bullet position faster?

The game runs at 20 ticks per second. If your motion is too fast for this, you have to check all the positions your entity moved through in one tick.

Say your motion is 5 blocks/tick then you need to check those 5 blocks, not just the current position.

ok, i've managed to fix my issue by getting the block hit coords and setting the entity pos to these hit coords, and its working

        else if(result.getType() == RayTraceResult.Type.BLOCK)
        {
            BlockRayTraceResult blockResult = (BlockRayTraceResult)result;
            hitx = blockResult.getPos().getX();
            hity = blockResult.getPos().getY();
            hitz = blockResult.getPos().getZ();
            this.setRawPosition(hitx, hity, hitz);

The impact effect is always reacting as expected, but sometimes, rarely, particles dont spawn, but the sound effect does play properly, so thats a bit weird.

I looked through your code, and I feel like you need to check IBlockReader::rayTraceBlocks and ProjectileHelper::rayTraceEnitities methods.
