GPS

[acp___(PL)]

Easy to script, if someone has a basic knowledge:

a) height at which there is a checkpoint;

b) direction to the next checkpoint (graphical indicator);

c) distance to the next checkpoint.

ad.a) 1- being above the positive value of the difference in hight

ad.a) 2- being below the negative value of the difference in hight

In MTAGUS I wrote scripts*, but with this I give up

I'm working and I don't have enough time for play MTA:SA

*) 20 best times on the map; expanded scoring system for winning races, taking into account the length of the race, the number of players, etc.; etc. ...

What is wrong?

... and no number on the screen are displayed ...

setElementData (source, 'next.checkpoint', ncp)

i think it should be 'source' there.

[acp___(PL)]

work only one thing:

outputChatBox ( "Cp number: " ..ncp, source, 0, 255, 0, 255 )

22-35 in gps_s.lua I added just because I wanted to check if the in chat box will appear

already forgot about this topic: P

text would not appear, enough to add it and it's working:)

Now I have to do arrows indicating how to display the direction to the cp ...

[acp___(PL)]

I do not know why this happens - arrows (see minimap) indicate the direction to the next CP (as in GPS)

arrow once pointing at the correct direction

once pointing at the inverted 180 degrees direction
