If yes, is there something special with such an array? Thanks for reading, thinking, answering

I use this in other functions too and they work fine. Could it be that the line at the end of this post is the problem? ent_tmp is a pointer to an entity, too. Is this a misstake? Code: next1[0] = ent_tmp; Last edited by Toryno; 07/15/10 19:47. Thanks for reading, thinking, answering

But be aware that skill70 is skill[69], not skill[70] (because it begins with skill[0] ). If ent_tmp points to a valid entitiy it should work. To be totally sure, you should make all ENTITY* pointers be NULL when they don't point to an entity. Then you can alway check if(entitiy) to see if it's valid. Kubetris LBGUI

Code: #define connect skill ... while(next1[j].connected[i] != 0) { } it should be: Code: #define connect skill ... while(next1[j].connect[i] != 0) { } or Code: #define connected skill ... while(next1[j].connected[i] != 0) { } Visit my site: www.masterq32.de

Thank you =D @Richi007: I just wrote "#define connected skill" in the editor, only a typing mistake while i posted this post. I will change it if someone read this post later Last edited by Toryno; 07/15/10 19:47. Thanks for reading, thinking, answering

Directly after the declaration of the array the lines work fine but later, when the array has changed always, I want to clear it with this lines but it crashes. Code: ENTITY* next1[50]; for(i = 0; i < 49; i++) { next1[i] = NULL; // no problem here } ... next1[0] = an_entity // example ... for(i = 0; i < 49; i++) { next1[i] = NULL; // here it crashes } Last edited by Toryno; 07/15/10 23:03.
