As i said in the title, i have some problems letting my custom controlled vehicle entity drive up blocks. I tried to achieve this like this:

int x=Math.sin(Math.toRadians(rotationYaw);
int z=Math.cos(Math.toRadians(rotationYaw);

if(worldObj.getBlockState(this.getPosition.add(x,0,z)).getBlock() !=Blocks.air &&worldObj.getBlockState(this.getPosition.add(x,1,z)).getBlock() ==Blocks.air){
   motionY=1;
}else
{
    double fullspeed=Math.sqrt((motionX*motionX)+(motionY*motionY));
    this.applydamage(fullspeed);
}

 

But what happens is that the entity is inside of the block and then outside of the world. I think something is wrong with the collision somehow. cuz the entity does not collide with blocks or entities. Also i think in my movement algorythm is something wrong(in the onUpdate() method), but i can't figure it out. This is the complete entitity class(Without the driveup blocks stuff):

Thanks for taking the time too help me

Anyone?

Try setting stepHeight to 1 or more

this.posX += this.vehicleX;
this.posY += this.vehicleY;
this.posZ += this.vehicleZ;
this.setPosition(this.posX, this.posY, this.posZ);

Why do you add vehicleX/Y/Z to the position?

This is the motion stored on the client to be set for the server, cuz i use keybindings to control the entity. Also, the entity extend Entity and not EntityLiving, so does stepHeight even affect it then?

No, don't just add motion when key is pressed. You should check collision before changing position.
