im thinking of making a sp map where at the end u have to fight a scarab like on halo 2 but with it blowing up at the end by u boarding it i just dont know how to can any1 plz help me cant even make a multiplayer map im gonna start if no 1 helps me

Halo's BLAM! engine doesn't allow players to stick on to vehicles, so a scarab fight onboard would be impossible.

Unless you made it so the Scarab was sitting still.

im not say u board it during the level like h3, im say like on halo2 the scarab come to a stop and at the end im makeing it so when it stopped thats when u board it

Yeah that would be possible, but I would put the ai in seats and when it reaches the stop they get out.

What I cannot figure out is how you can stick to those... engine core covers..? ... on the last level of halo 1... when they are moving. Maybe you can stick to scenery or devices or something... what if the scarab were a scenery/device like that?

devices, people talk about if they go sideways to fast people fall off, and scenery is the exact same as a vehicle (ive attached a bubble scenery to a person before; when they where moving, things could go threw it) Also, anything moving slow enough can have people still stand on them.. like play covie-cruser, and get the covie fighter bomber threw its object name.. let someone jump on it while your flying, and only move with jump, crouch, and tilting (tilting will make it move in the tilted direction) So, unless its going slower than the crouch movment speed, your not realy gonna have much luck.

once ived used chimp and grablistener what do i do?
i just need to use sapien to continue the maps creation.

and what do i type do make the scarab walk through the level and stop to attack tanks and pelicans then continue walking till being blocked by a cliff?
like on h2 when the scarab stops then fires at the tank and continues on????
