Backlog: HOOKS for Enable Vehicle Sun Glare Effect
January 2, 2022 / episodes
Well, this is a backlog note for enabling or disabling the vehicle sun glare effect presented inside the SA engine, it’s a VC leftover, well some of the memory addresses are lacking documentation e.g. 0x6ABCFD and 0x6ABD04 , if you guys are interesting, welcome to investigate, a good start may from RE3 source.
Known Address
- void CVehicle::DoSunGlare(void) 0x6DD6F0
- mid-function hook in CAutomobile::PreRender 0x6ABCFD (Source: CodeNulls)

December 28, 2021 / episodes
It’s a pretty old stuff made with CrystalMV, one of a legendary scripter in MTA commmnity. however, a few documentation were in there, of course, we do need a bit more understanding the basic of how this thing works before we can start doing some magic on that.
Description from CrystalMV’s site
Paths are made of path elements: nodes and connections and forbidden turns.
Node is the coordinate data. It is a white (or red, if highlighted) square with a black outline and a line of direction vector.
Connection is a link between two nodes which contains traffic type, density, lane count and speed parameters. It is a group of arrows for every lane, or a line if there is a single two-way line. Their color depends on the traffic type and transparency depends on density. A number indicating the speed limit is drawn on the connection. Starting and ending points of the arrows are on the lines of direction vectors of nodes. End points of the connection may have traffic light markers which switch their color between green and orange depending on traffic light state. These markers are lines which go in the direction dependent on which traffic lights they are for. For ped traffic lights they are vertical.
Forbidden turn is a link between two connections which disallows peds going along the first connection to turn to go along the second. Forbidden turn is displayed as two lines above the node. They go to the directions where the connections of the forbidden turn go. The line of the second connection has a cross on the ending point.

| Speed | unsigned integer (1 byte) | Value from 0 – 255, indicate the max speed limit when passing through the node |

[AWS IoT] Create a device to cloud connection with HTTP protocol
August 5, 2020 / episodesThe HTTP protocol has used rarely in the devices to cloud in the IoT industry. Professionals usually consider MQTT as the standard of messaging protocol used in the Internet of Things (IoT). Few articles have mentioned using HTTP for devices transmission protocols.
This article investigates AWS Rest API and conducts the study about the feasibility of the HTTP protocol used from devices to cloud.

MTASA PORT
This is a project that ports the LCS map into MTASA. I will try to make the map as much as close to the original LCS atmosphere by using the MTASA engine provided. Since the model was ported from a mod : Re: Liberty City Stories, therefore in here, I must give the credit to the original author Ryadica926 for a big appropriate of his hard work!
