well youve probably answered this a housand times but heres my prob

i have my code for collision detection

make object wall
set object collision on
make object collision box

make object monster
set object collision on
make object collision box

do
make monster walk around()

if object collision(monster,0)>0
x#=x#-(get object collision x()/2)
z#=z#-(get object collision z()/2)

position object monster#,x#,10,z#
rotate object monster,0,oldangle#,0
endif
loop

now for some reason it is still returning a 0 when the objects are colliding...

here is a snippet so u can identify how the distance function works.

It prevetns a lot of calls to the object collision and hit commands if used within the range of the object u are near.


see source button for the example

ok... umm problem is its not recognizing when there is a collision... i know how far away from the objects they are but do i need to calculate the distance too??

that will slow it down tremendously

wait i get what you were saying

ok ok i see your point and i will for sure use that

the problem im having though is not that its not doing the collision checks... its that when it is colliding with something the
object collision(obj,0) is still equal to 0 >> no collision

ok maybe this example shows u a little more insight to the problems u have at hand.

In order to acheive a sliding collision u have to add more to this example, Im focusing on the collision and hit commands to show u how to use them with a lot less checks compared to them not being checked by a distance function.

Without the distance function its going to be tooo slow for uasge unless your game or project only needs a few collision checks per round. thats boring tho so implement this feature and you may have to take a look at the sliding collision lesson 35 for that aspect.

see the additional example below to see how it works with the distance function.

ok so i went through the lesson there

it uses the exact same code as i do...

but never fear i got it working now, it had something to do with turning global collision off at the start of my prog

so i took that out and just set anything i didnt want detected off

yup thanks for your help though

im having another problem now
...its wickid hard to explain without being able to show ppl so you can download a demo of my game here
http://galileo.spaceports.com/~rochon/demos/m.zip

just walk around the level and it shouldnt take too long to find a monster.... now keep walking around and the monster starts doing some crazy things as soon as another one is in range, im just using a for/next loop to control the movement of all the monsters... anyone have a better way?

ok i got that daylight stuff sorted.

I donwloaded the demo but unfortunately it was very dark and I couldnt see if i was moving.

I noticed these keys by fumbling around

c character
i inventory (btw) nice work on the drag n drop item sprite matrix problems.
m map

Could you supply a method to make it brighter or is there a spell.?

Is there a readme with instructions?

It looks like your a lot further than I had suspected if I could only see it.

sorry mate its still jey black.

I can see 3 sets of numbers at the top left which the bottom one looks like a fps check (10 -20)

and I can see the bottom interface with 2 major colours red and blue shrouded by an orange noise bar.

I have a tnt2m64 so I cannot see any Transformation and lighting effects or shaders and so forth.

Could u post a screen shot to see what Im missing out on.

ok I held the mouse down and then I came across a very dark tile and found out that the starting position was in a black space.

The tiles are so barely visible and I didnt see a model in a 3rd person view so I cant tell if its 3rd person or more fps inclined.

there was no limiters to prevent me leaving the map into black space.

Thats what was throwing me.

I couldnt see a monster sorry its really dark,can someone else try this so we can evaluate this problem with lighting please.
