My models seem to keep sinking into the floor and walls, despite my having tried the following:

• Manually setting min_x, max_x, etc. to large values (~256).
  
• Compiling a level with large -narrow and -fat flags (~256,256,256).
  
• Manually setting the entity to .fat=1 and .narrow=0.
  

I'm using ent_move(), and at the moment, can't switch over to c_move(). Can anyone offer any pointers?

Thanks,

If you set -fat or -narrow values to "256,256,256", there will be huge collision boxes. So, if you set ".fat/narrow=on;", you'll need huge rooms to move in.
Look at your model's first frame in MED. Where is the centre?
Look at your model in WED, it's properties, its bounding box.
Look at your model in WED, zoom it in, move your mouse vertically/horizontally from edge to edge. What's the mathematical difference shown in the menu bar? That's the size you should base on with hull (level-building) or min/max (scripting) values.
Not sure if that helps.

Thanks for the info. The models in question are (I believe) 64x64x64, and have only one frame. I figured 256-cubed would be a good test to see if I could make absolutely sure that it never clipped into the walls, but it still seems to clip as though I'm using the default settings.

Am I missing something?

Thanks,

It would be really cool if someone could give a step by step process to setting hull sizes in the build options and in script, and explain what they will do for collision in wed. Some pictures to go along with it would be awesome. I seem to be struggling with this myself.

Thanks

I'd realy like to see how you both have your model set up in MED and the script your using to move your entity. I honestly have never realy needed to mess with an entities min_ max_ values

most the time that Ive had problems with an entity falling though the floor was because of 3 reasons

1 on terrains where the poly faces were realy too big to handle collision detection

2 when calculating hight from the floor (trace) don't compinsate for where the models orgin is... normaly this results becuse forgot UDE_BOX in the trace

3. my model is messed up in MED in respect to the origin. example I had similar problems with my cbabe model lately where she was half ways into the floor. what the problem was the FIRST frame was orintated correctly to the origin, but all the animation frames cbae was far below the origin. after realigning all my frames to the origin corectly the model works fine (selected frame 1 of the animation set frame range from frame 1 to last frame then moved the entity to correct location fixed all frames).

EDITED:

here is a simple pic how you should orintate your model to the origin in MED for ALL frames. You can rarely go wrong with the model if you keep it as centered on all 3 axis as possible



here is a simple move script I use for test levels for moving entities ( not including camera script) that works every time. if it doesn't work first thing to check is your entity.

Code:

	   move_mode = IGNORE_YOU + IGNORE_PASSABLE + IGNORE_PUSH + ACTIVATE_TRIGGER + GLIDE;

	   ent_move(move_vec,NULLVECTOR);

		

		If (move_vec[0] == 0  && move_vec[1] == 0)
