Sorry your browser is not supported!

I have been using dark gdk but when i try to collide with an object its not working i have my guy moving above the land but not stopping when i hit the object please help i tried for 2 weeks

I would suggest putting the old x/y/z positions into temporary variables, moving the object, checking for a collision, and if it is colliding, just move it back to where it was using the temporary variables.

We can help you if you include some source code of what you have so far

I answered a thread similar to this where i suggested the sparky sliding demo. I included some source , that should help, its what im using and it works fine.

this is my code it is pretty simple im beginning ill put full code on moday or tuesday im at a library dat means number ill get to it as soon as i can and fix it monday or tuesday im doing off memery
include "DarkGDK.h"

//terrain Functions i used the one in tutorials =(2)

dbLoadObject(ent.X,3);// this is beams to hold up the outpost
dbPositionObject(3,X,Y,Z);

//did this till 4 posts

dbLoadObject(top,9);

//camera functions that if you turn camera turns
dbPositionObject(1,dbObjectPositionX(1),dbObjectPositionY(2)+0.01f,dbObjectPositionZ(1));
// function that if colenel.X is on the plat form he stays on till
//he doesn't touch it anymore /still doesnt work



//moving functions



//collision stinks it move object up 50 ft away than instead of letting him collide then go up ladder.X
if(dbObjectCollision(1,10)==1)

I might be wrong for I don't use Dark GDK's built in collision system but don't you have to set each object up for collisions before the collision detection will work? Try testing out these:

im starting to learn sparkies but ill try what you have

now onto ai
