如何使用 OCaml 中的图形库移动图像？

Question

I'm programming in OCaml, and I use the Graphics library for the visualisation and Camlimages.

I have a moving element in the game, I would like to attach an image to it, the element have an x and y coordinates.

In the game loop, I have a function called display which displays on the screen the different elements of the game.

What I've done so far is including this in the display function of the element:

Graphic_image.draw_image image (t_x (x_ pos -. 20.)) (t_y (y_ pos -. 7.))

However my problem here is that the image is being duplicated at each frame.

My goal is to be able to avoid the duplication of the image at each frame or be able to move it.

How could I do that?

Thanks.

Putting clear_graph at the beginning of your main render function should be sufficient. Can you provide a more complete outline of what's going on in that?
