It is extremely simple to add objects to the world in Ragnarok. All you have to do is create the object and call add_obj from the Ragnarok engine instance. Below follows a more in-depth example:
A Sprite is essentially a container object for an image that allows us to manipulate properties of it extremely easily. Let’s start by creating the object.
sprite = R.Sprite()
Since we are adding only one object to the world, the update and draw orders don’t carry much significance as of yet. But if we were to add more than one object, these values would be responsible for controlling the order in which the object updates and draws in relation to other objects.
sprite.update_order = 0
sprite.draw_order = 0
Now we assign an image to the sprite by going to the Ragnarok Engine folder and pulling out its logo image.
Now, remember in the previous tutorial how we said that the World is the entity responsible for
managing our objects for us? Well, the last step to get this object onscreen is to
add it to the world so it can be drawn and updated.
Boom! That’s all it takes to get an sprite on the screen. You can play around with the sprite’s coords, scale, and rotation properties to change the orientation of the sprite accordingly.
