Hi, You are passing wrong arguments to DrawTexture function.

C DrawTexture function definition

RLAPI void DrawTexture(Texture2D texture, int posX, int posY, Color tint); 

Example

 
include flags.e 
include std/convert.e 
include Euraylib.ew  
  
constant width = 800  
constant height = 450  
  
atom black = bytes_to_int({0, 0, 0, 0})  
atom yello = bytes_to_int({255, 255, 0, 255})  
atom white = bytes_to_int({255, 255, 255, 255})  
  
InitWindow(width,height,"Simple Texture")  
 
while not WindowShouldClose() do  
  
	BeginDrawing()  
  
	ClearBackground(black)  
	  
	-- 1 placeholder 
	-- 2 defalut font 
	-- 3 gLoadTextureFromImage("raylib_logo.png") 
	 
	-- we are passing font texture loaded by defalut (Index 2) 
	sequence texutre_info = {2, 150, 150, 1, 0} 
	DrawTexture(texutre_info, width / 2, height / 2, white)  
	 
	DrawText("This is Texture",1,1,20,yello)  
	  
	EndDrawing()  
	  
end while  
  
--UnloadTexture(tex)

end procedure
