If you would like to get this working along with mudzereli's deploy bicycle script. It is pretty simple to do
1) In mission files go to "overwrites\click_actions\init.sqf" and change it to the code below:
Just make sure you point it to the correct location of your "custom\player_selectSlot.sqf" file, that was made with the deploy bike script.
2)Now we need to add the code from "overwrites\click_actions\ui_selectSlot.sqf" and slot it into your "custom\playerselectSlot.sqf"
take this part of the code:
and place it above this line "_pos set [3,_height];" in the "custom\player_selectSlot.sqf"
Then you should be all good to go. Not very good at writing guides, so go easy on me!
