Hi, sorry if i'm making dumb questions. I've programmed mods on GTA SA for 5 years, but when i say 5 years, i mean 1 year modding and other 4 doing almost nothing, and then i got back now.
Though i did some sucessful mods and missions, i got stuck with a project i always wished to work: recording the path of a vehicle and being able to reproduce it in any vehicle.
So, the first method i applied was just making an array of floats to save the vehicle positions, and then reproduce them later. I did a small one, and it worked.
Then i sophisticated it, i made bigger arrays, made it save the Z and Y angles (there is no opcode for the x_angle) and the speed, used it to smooth the movement, so the vehicle would be moving while it jumps between the positions.
The problem is: The code seems to run very slowly, it crashes if i make any array with more than 400 floats, and it also present several bugs, like jumping to coordinates that have nothing to do with the path recorded (and they aren't 0,0,0 too, they seem pretty random). I've checked the order of the variables to ensure that nothing was getting mixed, and nothing was.
When making bigger arrays, the code crashes on the recording, after some seconds have elapsed.
Can anyone help me here? Thank you!
Ps.: Do anyone know why the game doesn't start without a "wait" before all jumps on the code?. The loading bar of the game just gets stuck, i've tried everything, but, by the simplest the code can be, it'll still freeze the game if i don't put wait's before the jump's (and that include else_jumps too). I just put a "wait 0", i tried NOP's, and they don't work. I've suffered from it since i started, with different CLEO and GTA SA versions and installations, on differente computers and OS's.
