Healthbar manipulation
by Dameeuhn · in Torque 3D Beginner · 12/31/2013 (4:51 am) · 8 replies
So I have a datablock object called "TLogoItem" which is supposed to damage my player when I collide with it. Currently I created a GUI object for the healthbar in the PlayGui.cs file using the following lines,
I then added a onCollision function to my object "TLogoItem" so that upon collision the health value will decrease. However when I test it out, the object my player collided with gets deleted correctly however my healthbar still looks the same.
new GuiHealthBarHud() {
canSaveDynamicFields = "0";
Profile = "GuiDefaultProfile";
HorizSizing = "right";
VertSizing = "bottom";
position = "0 0";
Extent = "64 183";
MinExtent = "8 2";
canSave = "1";
Visible = "1";
hovertime = "1000";
fillColor = "0 1 0 1";
frameColor = "1 1 1 1";
damageFillColor = "1 0 0 1";
pulseRate = "500";
pulseThreshold = "0.25";
flipped = "0";
showFill = "1";
showFrame = "1";
displayEnergy = "0";
};I then added a onCollision function to my object "TLogoItem" so that upon collision the health value will decrease. However when I test it out, the object my player collided with gets deleted correctly however my healthbar still looks the same.
function TLogoItem::onCollision(%this, %obj, %col)
{
%obj.applyDamage(100);
%obj.delete();
}I would like to know how to make it so that when I collide with the TLogoItem object, the healthbar would actually drop so that I can see the fillcolor as well so I know that my health had dropped.

What might be the cause of the disappearing hp bar and player?

Oh yes! I didn't notice that mistake I made. I fixed the code however this time around my HP bar as well as my player disappears after collision. I set the applyDamage value as 10 instead of 100 which was what I set earlier. What might be the cause of the disappearing hp bar and player?

Damage is usually applied via the player datablock's own damage function rather than directly.

Death?Damage is usually applied via the player datablock's own damage function rather than directly.
%col.damage(%sourceObject, %position, %damage, %damageType);

What about the Max health values of the HP bar? I can't seem to find anything within the code which "sets" the health value. Since I used a value, 10, for the applyDamage method I would assume there's a default HP value or something around that I might have overlooked? I would like to modify the health values if possible at all.

It's probably automated in player.cpp on player creation - no point spawning a dead player!

and half of my health block got deducted so I'm assuming the max health value is "1"? I could work with that although if possible changing it to a larger value would definitely make my project easier.

Is there a slightly better hint? Do I have to assign the max health values by myself into the player datablock or somewhere within the onSpawn function? I tried%col.applyDamage(0.5);

I'm thinking (haven't checked) but if you use a fractional amount of health the system assumes you mean that fraction of the player's health, but I know that if you use an integer value it deducts that number from the player's health. So using 10 would take ten points but using .1 would take 10%....

Your max health is in the player datablock - in art/datablocks/player.cs. If you're using Torsion you can use ctrl-shift-f to search the whole project for "maxhealth".I'm thinking (haven't checked) but if you use a fractional amount of health the system assumes you mean that fraction of the player's health, but I know that if you use an integer value it deducts that number from the player's health.

It looks like you're applying damage to the object not the colliding player.
function TLogoItem::onCollision(%this, %obj, %col) { %col.applyDamage(10);//colliding player %obj.delete();//this object }See if that helps.
