If you set a hook at passable at Behavior in WED than the Enity goes trough walls ect. If there is no hook at passable the Enity goes not through walls.

none of the level has the passable flag set and ive tried with different maps but its the same.
when i copy the script to a project where c_move works it suddently doesnt work. and havent changed the models or anything only the script

It's obviously not a script problem, you have to post a demo (script+model+level), otherwise it continues to be a guessing game.

this script does not work for me. ive noticed that everytime i run a project it loads 4 dll's that it havent done from when i first got gamestudio. (ackphysx.dll, ackwii.dll, acknet.dll, ackAR.dll)

The wmp is missing...

Rebuilding the level solved the problem, thus your map compiler settings must be wrong. Click "Default Settings" once and rebuild your level.

thanks you that solved the problem!
