It's impossible to destroy Titanium/Uranium Ores by crashing with that objects

[ghost]

In previous GOLD and official Colobot versions you could destroy that objects by landing on them violently.

I propose that also Titanium, PowerCell, NuclearCell and OrgaMatter should can be destroyed in that way. KeyA..D and BlackBox should stay indestructible. TNT is also good as it is now.

According to the code, it should be possible, you just have to hit them hard enough:

    if (pObj->Implements(ObjectInterfaceType::Fragile))
    {
        // TODO: CFragileObject::GetDestructionForce (I can't do this now because you can't inherit both in COldObject ~krzys_h)
        DamageType damageType = DamageType::Collision;
        float destructionForce = 50.0f; // Titanium, PowerCell, NuclearCell, default
        if (pObj->GetType() == OBJECT_STONE   ) { destructionForce = 25.0f; } // TitaniumOre
        if (pObj->GetType() == OBJECT_URANIUM ) { destructionForce = 25.0f; } // UraniumOre
        if (pObj->GetType() == OBJECT_MOBILEtg) { destructionForce = 10.0f; damageType = DamageType::Explosive; } // TargetBot
        if (pObj->GetType() == OBJECT_TNT     ) { destructionForce = 10.0f; damageType = DamageType::Explosive; } // TNT
        if (pObj->GetType() == OBJECT_BOMB    ) { destructionForce =  0.0f; damageType = DamageType::Explosive; } // Mine

        if ( force > destructionForce )
        {
            dynamic_cast<CDamageableObject*>(pObj)->DamageObject(damageType);
        }
    }

That's strange, in official 0.1.6 builds that doesn't work.

I've just killed a bot, and Titanium was still "alive", even after some hits by Me. How much is bots destructionForce?

[krzys-h]

force = fabs(m_linMotion.realSpeed.x);
force *= crashSphere.hardness*2.0f;

Note that I'm not saying that it works for me because I'm terrible at aiming at such a small object :P

Also note that on collision the robot gets 1/200th of the force variable applied as damage (assuming damage is in range from 0 to 1/magnifyDamage)
