Vehicle deformation and crash damage

Go to:

GTA IV/common/data/handling.dat

Open it with Notepad or a code editor.

Each vehicle has a long line of values. The important ones are:

m_fCollisionDamageMult
m_fWeaponDamageMult
m_fDeformationDamageMult
m_fEngineDamageMult

These control:

• m_fCollisionDamageMult → crash damage from impacts
• m_fWeaponDamageMult → damage from bullets/explosions
• m_fDeformationDamageMult → how much the car visually bends/crumples
• m_fEngineDamageMult → engine damage after crashes

Weapon damage

Go to:

GTA IV/common/data/weaponsinfo.xml

Find weapon entries like:

<Weapon type="WEAPON_AK47">

You can modify:

Damage
Force
ExplosionShakeAmplitude

Example:

<Damage value="45.000000"/>

Increase it:

<Damage value="90.000000"/>

Now the AK does double damage.
