Blockable Sprite That Causes Damage

Does anyone know of a coding tutorial that explains how to make a blockable sprite damage your health.

I know how to make a bo_damage sprite. But, I want something that will not disappear and also damage the player everytime he touches it..

Could of sworn that I read a tutorial about this somewhere and at sometime, but I just can't seem to find anything with this now...

I post a tutorial for blockable damaging object later
but hurting bo_ that doesn't disappear is easy to make...
In wl_agent.c in GetBonus() go to the very end of the function
(looks something like this):

Code:


        case    bo_spear:
            spearflag = true;
            spearx = player->x;
            speary = player->y;
            spearangle = player->angle;
            playstate = ex_completed;

    }
    StartBonusFlash ();
    check->shapenum = -1;
}


Change the final lines to this:

Code:


    }
    if(check->itemnumber!=bo_hurt) //bo_hurt is the damaging bo_
    {  StartBonusFlash ();
      check->shapenum = -1;
    }
}


This if-clause makes sure that the
hurting bo_ item won't be removed
if player walks over it...

Also you could define new special tile
(like the Endgame-trigger) and then make
something similar (also in wl_agent.c,
this time in function Thrust() add
this to the very end of the function):

Code:


if (*(mapsegs[1] + offset) == HURTTILE) //Define in wl.def.h
    TakeDamage(1,NULL);


For the blocking item that hurts you - you need to go to
the cmd_use() (also in wl_agent.c) and add a check wether
player is standing next to the harming item - take damage.

Thanks for the quick code . I will try and give this a shot whenever I get time. Oh, hehe, I almost forgot, this is also going to be an animated object with 2 frames of animation. I'm not sure, but I think this won't change things too much...
