Draw library

PichotM · October 24, 2019, 1:21pm

Since some people maintain to use scaleforms/DRAW_* natives it could be interesting a “draw library” inside fivem to:

be able to do more things
better perf
load external images with url

Examples (copy pasted from gmod’s wiki):

I know NUI remains better for cool menus / complex stuff
but it could be very useful for:

people not confortable with NUI
small HUD/screen effects

Example of things made with these things

uh, why does such a thing need to be built-in?

also

github.com

citizenfx/fivem/blob/master/code/components/extra-natives-five/src/DrawImNatives.cpp#L232




static void WrapThing(void* a1)
{
	g_origThing(a1);


	DoDrawCommands();
}


static InitFunction initFunction([]
{
	fx::ScriptEngine::RegisterNativeHandler("DRAW_IM_VERTICES", [](fx::ScriptContext & context)
	{
		auto count = context.GetArgument<int>(0);
		auto positions = context.CheckArgument<VertexPosition*>(1);
		auto colors = context.GetArgument<uint32_t*>(2);


		DoDrawImCommand(count, positions, colors);
	});


	fx::ScriptEngine::RegisterNativeHandler("DRAW_TEXTURED_IM_VERTICES", [](fx::ScriptContext & context)
	{

these exist, aren’t documented/finished (were used for an imgui-js prototype), go extend them/document them and write a framework on top of them if you wish

that + script2d ought to be sufficient however, or what specific needs do you have?

also a piece-by-piece:

what ‘more things’ would you want on top of arbitrary vertex soup/script2d natives?

there’ll always be native call overhead, if you want async rendering use nui

sounds horrible to manage seeing how messy REGISTER_STREAMING_FILE_FROM_URL or R* cloud texture manager are ;/

Nice, I’ll check what that is
