I have maded physic for model when he drop from air and so on but i need get when he cant go up in too vertical walls terrains and so on! If any can help then please!

Here is picture if any cant understand what i mean with that!



P.S. Sorry for bad english!

You may use normal vector
trace down and if normal > something don't go any further

Dont know if i understood your problem but if you made a physics script for your player you will have a vertical force (gravity). So if you want to climb terrains and so decrease that force or increase the steering forces.

Only one problem is taht when i havent idea about this! How to make!
I need any who can help with some code lines!

something like this

while(me)
{
vec_set(temp,my.x);
temp.z = -500;
c_trace(my.x,temp,IGNORE_ME|IGNORE_PASSABLE|IGNORE_SPRITES);
if(abs(normal) > 0.4){my.speed = 0;} //I've used abs to make this working both sides, I mean if slope is increasing or descending but You can change it to move faster is descending and stop if increasing to much
else{my.speed =5;}
c_move(me,vector(my.speed *time_step,0,0),nullvector,GLIDE);
wait(1);
}

edit: but problem is that the normal will be the same no matter what your pan will be.
So another idea is to tracing from 4 differents points (one front, one behind, one on the left and one on the right side of the plyaer) and checking differences between distances to the floor.
So if difference between distances to floor between front one and back one is to large (f.e. back one is higher than front one) it means you are on increasing slope etc
Then your speed can depend of differences. If slope is more increasing then slower the speed is.
I like this idea

disable z glide might help, you can specify the degrees but it depends on the size and origin of your models.
More can be found in the manual.
