I want to draw a square on my screen, I test it in listen server, so I do it in a metamod plugin, I succeed got the global cl_enginefunc_t * pointer,
g_pclengfuncs->pfnClientCmd("clear\n"); and some other functions works fine,
but
g_pclengfuncs->pfnFillRGBA(500, 400, 100, 50, 255, 0, 0, 255); didn't show anything, I wonder what's going on...

Good trying! I want to do this too.

	g_pclengfuncs = (cl_enginefunc_t *)(OFFSET_CLIENT_ENGFUNC);
	memcpy(&g_clengfuncs, g_pclengfuncs, sizeof(cl_enginefunc_t));
	
	wrect_t rc;
	rc.left = 500;
	rc.top = 400;
	rc.right = 600;
	rc.bottom = 500;

	HSPRITE_t hspr = g_clengfuncs.pfnSPR_Load("sprites/crosshairs.spr");
	g_clengfuncs.pfnSetCrosshair(hspr, rc, 255, 255, 255);

	g_clengfuncs.pfnFillRGBA(500, 400, 100, 100, 255, 0, 0, 255);

I can see the crosshairs spr, but the square don't show, weird

You should call pfnFillRGBA withing openGL draw frame (after R_SetupGL function call). For example from client functions HUD_DrawNormalTriangles, HUD_DrawTransparentTriangles, HUD_Redraw, ....

Thanks for the tip, I've already figured it out after reading some cheat source. But still thanks for making it clear.
