Hi,

I have finished wrapping Raylib 5.5 for openEuphoria. I've also added a simple animation example as well. The wrapper uses Greg's Euphoria FFI library. This allows the easy wrapping of C style structs.

https://github.com/gAndy50/EuRayLib5

include std/ffi.e 
include raylib.e 
 
constant MAX_FRAME_SPEED = 15 
constant MIN_FRAME_SPEED = 1 
 
constant WIDTH = 800 
constant HEIGHT = 450 
 
public enum tex_id, 
	 tex_width, 
	 tex_height, 
	 tex_mipmaps, 
	 tex_format 
 
InitWindow(WIDTH,HEIGHT,"Sprite Animation") 
 
sequence scarfy = LoadTexture("scarfy.png") 
 
sequence pos = {350.0,280.0} 
sequence frameRec = {0.0, 0.0, scarfy[tex_width] / 6, scarfy[tex_height]} 
 
integer currentFrame = 0 
 
integer framesCounter = 0 
integer framesSpeed = 8 
 
SetTargetFPS(60) 
 
while not WindowShouldClose() do 
	framesCounter += 1 
	 
	if framesCounter >= 60 / framesSpeed then 
		framesCounter = 0 
		currentFrame += 1 
		 
		if currentFrame > 5 then 
			currentFrame = 0 
		end if 
		 
		frameRec[1] = currentFrame * scarfy[tex_width] / 6 
	end if 
	 
	if IsKeyPressed(KEY_RIGHT) then 
		framesSpeed += 1 
		elsif IsKeyPressed(KEY_LEFT) then 
			framesSpeed -= 1 
	end if 
	 
	if framesSpeed > MAX_FRAME_SPEED then 
		framesSpeed = MAX_FRAME_SPEED 
		elsif framesSpeed < MIN_FRAME_SPEED then 
			framesSpeed = MIN_FRAME_SPEED 
	end if 
	 
	BeginDrawing() 
	 
	ClearBackground(RAYWHITE) 
	 
	DrawTexture(scarfy,15,40,WHITE) 
	DrawRectangleLines(15,40,scarfy[tex_width],scarfy[tex_height],LIME) 
	DrawRectangleLines(15 + frameRec[1],40 + frameRec[2], frameRec[3], frameRec[4], RED) 
	 
	for i = 1 to MAX_FRAME_SPEED do 
		if i < framesSpeed then 
			DrawRectangle(250 + 21 * i, 205,20,20,RED) 
			DrawRectangleLines(250 + 21 * i,205,20,20,MAROON) 
		end if 
	end for 
	 
	DrawTextureRec(scarfy,frameRec,pos,WHITE) 
	 
	EndDrawing() 
end while 
 
UnloadTexture(scarfy) 
 
CloseWindow()

Thanks for the support. I'll add the FFI library into the repo.

I think the "proof of concept" is working. Libffi has been great for Euphoria and for wrapping libraries.

xrlTranslatef = define_c_proc(ray,"+rlTranslatef",{C_FLOAT,C_FLOAT,C_FLOAT,C_FLOAT}), --4 parameter 
xrlRotatef = define_c_proc(ray,"+rlRotatef",{C_FLOAT,C_FLOAT,C_FLOAT}),               --3 parameter   

xrlTranslatef = define_c_proc(ray,"+rlTranslatef",{C_FLOAT,C_FLOAT,C_FLOAT}), --3 parameter 
xrlRotatef = define_c_proc(ray,"+rlRotatef",{C_FLOAT,C_FLOAT,C_FLOAT,C_FLOAT}), --4 parameter 

RLAPI void rlTranslatef(float x, float y, float z);   // Multiply the current matrix by a translation matrix 
RLAPI void rlRotatef(float angle, float x, float y, float z);  // Multiply the current matrix by a rotation matrix 

Good catch. I have fixed it. It is now correct on the EuRaylib 5.5 repo.
