The textdraw editor is merely for creating the visual part of the textdraws - that is, if you are creating a phone, for example, you would create various box-shaped textdraws in order to make the body, screen and other features of the phone. Then you would type in normal text draws for the buttons and letters. Finally you create a base for the menu. After the visual part is done, the final and ultimately most important part is start scripting and bring your textdraws to life!
All of the menu, audio, navigation and other functions shown in the video you linked are done through PAWN scripting. The TD editor is only used to create the visuals.
Alright and how does the bringind the textdraws to the life work? It is literally like detecting keys and hiding/showing new textdraws? Is not that too much lines of code? Because from the point that I understand how it works, it needs to be sooo much work.
One more question just to add. If I want to do for example casino features, how to include like Singleplayer pictures of for example that coin winning machine, where you have to match 3 results in order to win? For example 3 golden bricks?
Thanks!
