Creating an antlion attack?

Okay. Here's my problem. I'm making a Starship Troopers based
singleplayer map and I've got my little outpost and on the other side I
have npc_antlion templates and npc_antlion_template_makers. They spawn
the antlions perfectly, but the antlions are just plain dumb and will
not attack until I am within several meters. This is a huge issue
because they're supposed to run across the map towards the outpost.
Instead they stand there and wait for me to get REALLY close to them.
Is there any way I can make them always going after the player or even
better, trying to get to the center of the outpost? I've tried a few
things, like aiscripted_sequence, and none of them seem to work. Could
I be using them wrong or is it because I'm using the template maker.
Thanks in advance for any help

here i say how you can have fun in a hl2dm map the same is possible in a sp map

did you place info nodes? for the antlions to navigate?

Thanks, but for some reason they absolutely will not follow the nodes,
no matter how close I put them. So I had to reject the answer. They
just stand there looking at me till I get within range, then they do
attack.

Did you apley a AI_relationship to the antlionguard?
