Maybe this
PHP Code:
set_pev(ent,pev_movetype,MOVETYPE_STEP)
or
PHP Code:
set_pev(ent,pev_movetype,MOVETYPE_PUSHSTEP)
However, there's a risk that the medkit will fail under the textures.
By the way, I'd look at the alternative to replace the standard DeathMSG in support of #include hamsandwich and Z-Bot Spawn Bitparser ('cause with certain changes, DeathMSG will crush the server). But this requires any time for realize this yet the only damned bug.
