debugscript message

[MAB]

i am making a speedometer and i found something very strange.. a debugscript message.. comes when there is not nitro in the vehicle that the player is in

Error:26: attempt to perform arithmetic on local 'nitro' (a boolean value)

although i did "if getVehicleUpgradeOnSlot(veh, then" it still coming

note: when i put nitro on the vehicle ... the "currenthealth" progress bar color works but when there is no nitro that color turns white and that is because of that debug message..

also i need help in the speed progress bar.. what should i do in the width? i am tried with it

I think the function returns false even if the upgrade exists. As long as the nitro level is zero, it returns false.

local nitro = getVehicleNitroLevel(veh) or 0 

This should omit the error.

Bravo.. you were right and there is no message now

does anyone know what to put in the speed progress bar argument?

[JR10]

I don't understand. Are we talking about the width of the progress' rectangle? If so, just calculate the width based on the percentagle.

local width = progress * max_width

nvm i done it
