For some reason when moving an NPC with solid slide & move type (STEP/PUSHSTEP) the NPC doesn't display movement rather shows the NPC at the start and the end period, it doesn't display it walking to the end point, any thoughts?

Entity has the flag FL_ALWAYSTHINK which help inform clients about the entity location and velocity.

You have to call StudioFrameAdvance or use an entity base that already does it. Or use MOVETYPE_PUSHSTEP instead of STEP.

I already changed entity move type to MOVETYPE_PUSHSTEP and still it doesn't work.

[HamletEagle]

It should, show some code.

Solved, apparently setting pev_impacttime effects the entity model in someway.
