Все скомпилил, краба на карту поставил запустил карту вот что было написанно в консоле после того как я подошел и отошел от краба:
JumpAttack!JumpAttack!JumpAttack!JumpAttack!
npc_headcrab thinking for 44.55ms!!! (SCHED_CHASE_ENEMY); r43.81 (c0.15, pst0.00, ms43.65), p-r0.04, m0.65
npc_headcrab thinking for 25.44ms!!! (SCHED_CHASE_ENEMY_FAILED); r25.34 (c0.13, pst0.00, ms25.21), p-r0.04, m0.01
npc_headcrab moving with speed <= 0 (Run1)
npc_headcrab moving with speed <= 0 (Run1)
меня интересует вот эта строка: moving with speed <= 0 (Run1) где я должен указать скорость перидвижения?
Почему краб не двигается по миру?
И почему краб все время поворачивается ко мне боком когда замечает меня?
