This will work !
"es es_xgetplayerlocation wcs_x1 wcs_y1 wcs_z1 event_var(userid);es est_effect 11 #a 0 sprites/flatflame.vmt server_var(wcs_x1) server_var(wcs_y1) server_var(wcs_z1) server_var(wcs_x2) server_var(wcs_y2) server_var(wcs_z2)50 450 2 10 200 3 124 134 144 255 1"
No It's not gonna work because you used:
GeSHi (eventscripts):
server_var(wcs_x2) server_var(wcs_y2) server_var(wcs_z2)
but there isn't any "es es_xgetplayerlocation wcs_x2 wcs_y2 wcs_z2 event_var(attacker)" or "es_getplayerlocation wcs_x2 wcs_y2 wcs_z2 event_var(attacker)"
you missed an space before the numbers get started
GeSHi (eventscripts):
server_var(wcs_z2)50
and why you changed to est_effect 11 ? this syntax only has 3 numbers
