It seems that "CollisionFree()" changes position of an actor. The moveto() function which is executed afterwards
moves even if I specify "0" as value.

Has anyone expierience with the "collisionfree()" function?

Thx

int n;
Actor *actors;

char *key = GetKeyState(); //Get entire keyboard state

if(xvelocity == 0 && yvelocity ==0)
{
if(key[KEY_RIGHT] == 1) //Test if right key is pressed
{
CollisionFree("Event Actor", x+32, y);

actors = getAllActorsInCollision("Event Actor", &n);


if(n==0 ||(n==1 && !strncmp(actors[0].name,"ground",6)))
MoveTo("Event Actor", 0.000000, 0.000000, 4.000000, "hero", "");
}

if(key[KEY_LEFT] == 1) //Test if left key is pressed
{
CollisionFree("Event Actor", x-32, y);

actors = getAllActorsInCollision("Event Actor", &n);


if(n==0 ||(n==1 && !strncmp(actors[0].name,"ground",6)))
MoveTo("Event Actor", 0.000000, 0.000000, 4.000000, "hero", "");
}

if(key[KEY_UP] == 1)
{
CollisionFree("Event Actor", x, y-32);

actors = getAllActorsInCollision("Event Actor", &n);


if(n==0 ||(n==1 && !strncmp(actors[0].name,"ground",6)))
MoveTo("Event Actor",0.0,-0.000000, 4.000000, "hero", "");
}

if(key[KEY_DOWN] == 1)
{
CollisionFree("Event Actor", x, y+32);

actors = getAllActorsInCollision("Event Actor", &n);


if(n==0 ||(n==1 && !strncmp(actors[0].name,"ground",6)))
MoveTo("Event Actor", 0.0,0.000000, 4.000000, "hero", "");
}
}

try using xscreen and yscreen, unless you mean it changes visual position aswell.

I personally have only used collision free as a conditional statement.

Code: Select all

if(CollisionFree("Event Actor", x+32, y))
{
//do some stuff
}

Doubt that really helps anything...

EDIT: for get all actors in collision, it seems to avoid problems to reset your actor variable every time you use it so it doesn't get confused and think there are still actors - so second line should be

Code: Select all

Actor *actors=NULL;

I am pretty sure its a bug. Collisionfree() shouldnt impact anything.
