is it possible to approach a block, and see if its height (from my players height, to the top of the block) is under a certain number? I have some theories.. but they dont work... basically I have this to start >>
///.. Checked to see if the player is infront of a block
if(trace_hit!=0){
if(you==null){//you are a wall
jump_obstacle=1;
}
}
now since the block is not an entity, the 'you' pointer doesnt work.. so doing this:
///.. Checked to see if the player is infront of a block
if(trace_hit!=0){
if(you==null){//you are a wall
if(vec_dist(my.z, you.max_z)<25){jump_obstacle=1;}
}
}
gives me an empty pointer error any ideas? .. Please  Edit: the reason why I would like this is because my player will check to see if the block infront of him is a valid block to jump up onto.. if its higher than 25, he shouldnt jump.. maybe this is some better info?

Just an idea:
select a point inside the volume near the hit point ( e.g. adding the inverse normal). Now trace upwards. You can check this result for:
the trace hit nothing: it was an outer level wall
the trace hit a backside face: it is a block with a topside check the value wether it has the required height
the trace hit a frontside face: no clue what happens at this point

K I just can't figure it out!!!!!!!!!! I've been trying every which way to do this and still nothing... the closest thing i can come up with is this: But first, this code checks to see if my player is infront of a block, and if so then turns on the jumping var:
vec_set(checkaheadtemp,vector(5,0,0));
vec_rotate(checkaheadtemp,my.pan);
vec_add(checkaheadtemp,my.x);
trace_mode = ignore_me + ignore_models + ignore_sprites + use_box;
result = trace(my.x,checkaheadtemp);
if(result>0)&&(vec_dist(my.x,links_temp_jump_pos.x)>5)&&(link_on_ground==0){jump_obstacle=1;}
--------------- now this code, is my attempt at figuring this problem out.. but it works in the reverse, So if the block is higher than my players max jumping height, my player jumps..
vec_set(checkaheadtemp,vector(5,0,0));//check in front
vec_rotate(checkaheadtemp,my.pan);//in front of me
vec_add(checkaheadtemp,vector(my.x,my.y,my.z+25));//store my.x to my.z + trace height
trace_mode = ignore_me + ignore_models + ignore_sprites + use_box;
result = trace(vector(my.x,my.y,my.z+25),checkaheadtemp);
if(result>0){
vec_set(checkaheadtemp,vector(5,0,0));
vec_rotate(checkaheadtemp,my.pan);
vec_add(checkaheadtemp,my.x);
trace_mode = ignore_me + ignore_models + ignore_sprites + use_box;
result = trace(my.x,checkaheadtemp);
if(result>0)&&(vec_dist(my.x,links_temp_jump_pos.x)>5)&&(link_on_ground==0){jump_obstacle=1;}
}
any more ideas?

okay.. I have another idea... but dont know where to go from here. Basically:
vec_set(links_temp_jump_pos, vector(my.x,my.y,my.z+25));
c_trace(my.x,links_temp_jump_pos,ignore_me+ignore_models+ignore_sprites+use_box);
-store the height from link to "above link +25" -then trace between link, and the stored array. now i need to check to see if there is a block somewhere inbetween, otherwise it will just make him jump.. here is an image i made to help me ^_^

No dude, make it like this:
VECTOR end_pos;
vec_set(end_pos,vector(10,0,my.max_z + 10));
vec_rotate(end_pos,my.pan);
vec_add(end_pos,my.x);
c_trace(my.x,end_pos,IGNORE_ME|IGNORE_PASSABLE);
if(trace_hit){/* DON'T JUMP*/}else{/*JUMP*/}
This is not tested, but should give you an idea. This is same as making player climb things, but there you would need second trace from players center.
