Melee/Collision/Damage

by Edward · in Torque Game Engine · 02/09/2007 (8:51 am) · 6 replies

I am currently working on my project, and i am at a small snafu. I want to have a AI player that needs to attack aplayer. However, the issue is i want any collision with the AI player to cause damage tothe player. THink for example a rolling ball, any impact on a player, there isnt a single mounting point for weapons (which would be easy) but i want the entire Collision box of the AI to damage the player. so if it were to fall on a player or the player were to get too close.

Any ideas on the best way to do this. btw there is a animation that needs to play while each contact is made.
I have looked in several of the melee, andalmost all of them require a mount point and a melee weapon. just to clearify, what if a player wanted to ram a object with a vehicle ala collision detection to infict damage.

    It's not very clear what you're asking here. It sounds like just simple damage infliction, i.e. not separate hit areas or anything. In which case, would the standard collision callbacks not be all you need? -- just apply damage and start animations from inside those functions?

    Yes, that is what i am thinking, but modifying the ::onCollision for those functions are a bit beyond my skill, expecially when i want to play animations. They really need to update the melee sections.

    Sorry, I know nothing of the 'melee sections' nor why they're relevant to collision-based damage calculations..

    Unless I'm totally missing your point, Sam provided you with you best solution, which actually doesn't require much skill to use

    In the script containing your AI objects and definitions:
    function AIPlayer::onCollision(%this, %obj, %col)
{
     if(%col.getClassName() $= "Player")      [b]// Check to see if we are colliding with player[/b]
     {
            %this.playThread(0, "damageAnim");         [b]// Animate AI unit[/b]
            %col.applyDamage(20);                              [b]// Hurt the player[/b]
     }
}

    Thats what i was lookign for lol i had managed to piece together something similar, its the other jargon that i was missing.


    function MonsterA::onCollision(this,%obj,%col)
    {
    %objectVelocity = %obj.getVelocity();
    directDamage = 20;
    areaImpulse = 10;
    }

    so for a non-programmer i was in the right track. Thank you Michael.
