I have a problem where enemy models won't face the right direction. I have tried rotating them, with no avail, and i also had no luck rotating what they were pointing at.

The code i used to point them at the object is as follows
CODE

dbPointObject (1,dbObjectPositionX(2),dbObjectPositionY(2),dbObjectPositionZ(2));
dbMoveObject (2,1.0f);


This will move the object in the write direction just fine. But the sprite itself is facing the wrong direction. This code is in the While loop. As i said before i have tried rotating object 1 and object 2 but it didnt seem to change anything.

Much help appreciated.

Does the object rotate at all? or will it only move in the direction you point it at?

The Object doesnt seem to rotate. I've tried to get it to rotate but it only point in the wrong direction.

Reread his post..

Stayscrisp is asking if the object will rotate.. not point at a specific direction but just rotate around in a circle. Can you get the object to physically change which way it is facing?

Also a separate question you need to answer:
Does the object ONLY move in the direction it is facing? Assuming you can rotate it, does it then move in the same direction as before? Or did the rotation change which way it moves...


What language is that?

The language he is using is Dark Basic

This is a good place to start with some vector mathematics smile.gif http://www.euclideanspace.com/maths/algebr...ookat/index.htm

Its hard going though, but don't get overwhelmed, just read it over a few times.

If you want something easier though, there are rotation libraries that plug directly into DarkGDK

like this

But where's the fun in that tongue.gif

Good luck.

I see what he's asking now. Yes i can make it rotate, but when i do it does not move in the correct direction. It is infact DarkGDK ( DarkBasic is very similar) and i will look into the links you provided when i get a chance. Thanks!

I just thought of something, when I was using Irrlicht one time the math was correct and the model rotated but wouldn't move in the correct direction, it actually had something to do with the model itself and the way it had been rotated before being exported.

That may help you if you can get it into a 3d Model program and rotate it to a different facing direction.
