you don't need this timer to hide textdraws:

Code:

SetTimerEx("CheckPlayerStatsKeys", 200, 1, "d", playerid); //setting timer for checking player keys

you can hide textdraws by using OnPlayerKeyStateChange
and this:

Code:

new tdstring[512];

shoul be:

Code:

new tdstring[128];

because max input and output in samp is 128
