Functions that require pointers signal error about cl-raylib

[longlene]

ok, I encounter the same problem with update-camera and still no way to use struct and pointer to struct at the same time.
Maybe implement update-camera in pure Lisp is a way?

check this example:

(defun input-keys ()
(let* ((screen-width 800)
(screen-height 450)
(ball-position (r::make-vector2 :x (/ screen-width 2.0) :y (/ screen-height 2.0))))
(unwind-protect
(progn
(r:init-window screen-width screen-height "raylib [core] example - keyboard input")
(r:set-target-fps 60)
(loop
:do
(when (r:is-key-down +key-right+)
(setf (r::vector2-x ball-position) (+ (r::vector2-x ball-position) 2.0)))
(when (r:is-key-down +key-left+)
(setf (r::vector2-x ball-position) (- (r::vector2-x ball-position) 2.0)))
(when (r:is-key-down +key-down+)
(setf (r::vector2-y ball-position) (+ (r::vector2-y ball-position) 2.0)))
(when (r:is-key-down +key-up+)
(setf (r::vector2-y ball-position) (- (r::vector2-y ball-position) 2.0)))
(r:begin-drawing)
(r:clear-background r:+raywhite+)
(r:draw-text "move the ball with arrow keys" 10 10 20 +darkgray+)
(r:draw-circle-v ball-position 50.0 +maroon+)
(r:end-drawing)
:until (r:window-should-close)))
(r:close-window))))

I'll close the issue as camera related API should be usable now.
