@alexander blade -
its a wonderul thing that the scripthook as already out. that's fantastic.
but there is something i hope you will consider:
It's 2015, and unlike 2008, ppl today are playing GTAV on laptops or on TVs with controllers (and wifi keyboard that also do not have numpad). The trainer does not support keyboard that do not have a numpad nor a controller. i am one of these people but there are plenty like me.
I hope will you will be able to modify the scripthook to allow full interaction with mods via the controller.
In this trainer's case i can offer some solutions for example:
holding down on the D-pad (the character selection button) + holding down the right bumper or the "menu" button (the equivalent of ESC) will bring up the neat interface of the trainer. and when the interface is up then the D-pad will control the trainer interface and NOT the phone. the button A will be for selecting.
on a numpad-less keyboard maybe you can bring up the UI by pressing F5, and unlike F4, pressing F5 will allow the arrows and ENTER to control the UI and also bring up the MOUSE cursor to manipulate the trainer. this has a slight disadvantage compared to the numpad control but it's a small sacrifice.
These are mere suggestions on how to make mods and this trainer more accessible, and im sure that you can come up with more good ideas. these were just mine
as it stands - certain ppl will just not be able to use the trainer and perhaps not even the upcoming mods because a lack of support of their favorite control scheme.
I think it's worth a thought.
Wonderful job, mate. it's great having you aboard once again!!
